Re: Create comma separated list from all rows in a column (not a CSV file)

Sounds like you are ok with taking the data from the table row by row, so the issue is overwriting the data that already exists in the Text Input field.

I suggest that you consider the logic that is as follows:

Set Field ‘Text Input’ = ‘Text Input’ + comma + New Data from table

That way the new data should be added to whatever is already in the Text Input object.
