I have a column that contains two locations from the extract, there is another column that indicates if they are in both locations.
I want to combine this into a single column.

I wrote a formula, also tried this in a multi-row formula with the same results, that in essence is:
IF [InBOTH] = 'Yes'
THEN [Data Source] = 'In Both'
ELSE [Data Source]
ENDIF
Which ends up putting zeros in the Data Source column instead of the string I would like there.
I've tried several iterations of the same logic with the same results.
