I have a number of Sentinel workbook queries where I click on a value in the 1st query which is then exported as a parameter to be used in a 2nd query. This is working great except when the workbook is first loaded, because I haven’t clicked on anything in the 1st query, the 2nd query displays the following error. How can I specify a default value to satisfy the query until I click on a value?

Query could not be parsed at ‘)’ on line [2,21] Token: ‘)’ Line: 2 Position: 21

The first 2 lines of the 2nd query look like this:

let ActivityType = dynamic({AType});

Any help to resolve this error is appreciated.
