I have created an app in appdesigner and it has a dropdown. And I check the value of this dropdown to a string value.
function SelectBatteryDropDownValueChanged(app, event)
if app.SelectBatteryDropDown.Value ~= ‘none’
end
end
‘none’ is one of the values initialised to the dropdown. Now a select a value from the dropdown I expect the program to check first if the value is not equal to ‘none’ and if true execute some code. But It is giving an error :
Arrays have incompatible sizes for this operation.
This doesnt make any sense since both ‘none’ and app.SelectBatteryDropDown.Value are of type char, I checked to make sure. Yet this error is coming. Why is that? How can I fix this.
