VBA Form Command Button not working
I’m going out of my mind trying to resolve this issue. I have succeeded at creating and using macros without issue, yet all my efforts at testing a simple VBA form command button based on youtube instructions fall flat. I have spent several days researching every possible cause and solution without success. I have even gone as far as removing and reinstalling Microsoft 365, as well as factory resetting Excel by deleting Excel’s folder using RegEdit. My non-form macros work without issue. Yet creating a single form command button to general a VBA MsgBox fails to work. Please keep in mind that I usually have no difficulties resolving any problems that come my way. This time however, NOTHING!. NADA!

How can I change the cell colour of one cell based on either another cells’ colour OR value?
Hey guys!
Working on a personal study tracker, and would really appreciate any guidance/support on this step I’m trying to setup.
Note:
– Cells from Column D12 onwards below = date
– Cells from Column E12 onwards below = my score
I would like the cells in the D and E column, e.g. D12 AND E12 to change to the same colour based on the score in column E, which are as follows:: Cell scores: 0-2.5 = Red Cells; 2.5-4 = Orange Cells, 4-5 = Green Creeks
These cells in D & E should simultaneously change to the same colour, of which there are only 3 I need: Red, Orange, Green (as you can see in: E1:G2) – if it helps, each cells’ colour-index code is listed in cells: E5:G5 (in corresponding vertical order).
From looking into this, there’s a few ways to do this. I can either have column D change colour by either column E’s score OR cell colour. I believe the latter would work best and should be more straight-forward(?).
I’m confident in setting up the conditional formatting for column E by doing: Home>Conditional Formatting>Highlight Cell Rules>*Clicking the appropriate rule*>Input values and select background colour — but, this only deals with Column E; Column D wouldn’t immediately synchronise with this.
I’ve briefly researched into VBA (a whole new world!) & Conditional Fomatting>New Rule>”Use a formula… to format” — I’ve been able to wrap my head around the latter, but I’m not getting the result as I know I’m messing up with the formula.
ALSO, in case it’s worth noting. I have my Excel spreadsheet saved in ‘XLSM’ format instead of ‘XLSX’ as I was watching a VBA video for this and was informed to save the spreadsheet in this format. Not sure if this may impact any advice, hence the mention just in case.
I hope this makes sense! Happy to elaborate further if need ne.
Again, I really appreciate anyone whom takes it out of their time to help out. Many thanks in advance!

Supporting Women in the Data Center Development Realm – Women in Construction
With the amount of the Data Centers being constructed globally to support the Microsoft Capacity Business goals, as a former Microsoft DCD (Data Center Development) team member myself, I saw first hand how more women in the industry of construction require advocacy and sponsorship in their careers.

VBA module in Word Normal Template not saved
Hi,
Windows 10 64 bits, Office Professional 2016, Word
I code in VBA7, my module is in the Normal template. Since a few days, my module is not saved correctly in Normal template when I press Ctrl-S or use the menu. It looks like it is saved in a WRLxxxx file (that’s what I I see in the the VBA Editor window title), with xxxx looking random. I cannot find my code back in the Normal template at next Word session.
I tried this:
– repare Office function (didn’t work)
– quit Word, rename Normal.docm, restart Word (creates a new Normal.docm), import module in the freshly created Normal template (did’nt work)
– checked add-ons : no add-ons (except inactive OneNore add-on
Can someone help ? Thank you.
Kind regards,
Jean-Pierre

Counting A Column Uniquely Based On Another Column
I have a column (A) which I use check (ü) or false (û) ─ Wingdings font ─ to indicate whether people from column (C) are joined in group or not.
There are duplicates in the column (C), which I write people’s names in, hence there are duplicate checks (ü) or falses (û) in column (A).
I want to count checks (ü) or falses (û) without duplicate, based on column (C); since obviously every checks (ü) or falses (û) would be duplicated multiple times because they have no distinction like names!
I already have a formula for counting column (C) without duplicate which I share below:
=SUM(IF(FREQUENCY(IF(LEN(a2:a497)>0,MATCH(a2:a497,a2:a497,0),””),IF(LEN(a2:a497)>0,MATCH(a2:a497,a2:a497,0),””))>0,1))

Oh, the following function fftm in line 6, is a function downloaded by me, it’s a fft function modified, and you can see it below:
% Modified fft algorithm
%
% This function estimates the fft of a signal x using the Fs sampling
% frequency, NFFT bins, and returns the frequencies values along with the spectrum X.
%
% [X,f] = fftm(x,Fs,NFFT)
%
% Example:
% Fs = 1e3;
% t = 0:0.001:1-0.001;
% x = cos(2*pi*100*t)+sin(2*pi*202.5*t);
% [X,f]=fftm(x,Fs,2000);
% plot(f,abs(X));

f = 0:Fs/NFFT:Fs/2;Hello everyone!! I’m trying to plot: x,y,X,Y. But when my matlab try to plot y, the following error appears: Error using plot Vectors must be the same length. Error in doc (lne 94) plot(t, y);
Please fell free to check the code below:

T = 1/Fs;
t = 0:T:1-T;
NFFT = 2^nextpow2(length(t));
x = cos(2*pi*100*t) + cos(2*pi*500*t) + cos(2*pi*1000*t);
[X, f, ~] = fftm(x, Fs, NFFT);
H = double(f <= 600);
Y = X .* H;
y = ifft(Y);
