Just discovered a weird thing, not sure if this has come up before.
I was trying to use cint(row(“Box”)) in an expression builder in an Assign activity and was getting an error.
It turns out since I changed the font in the Excel spreadsheet it was throwing an error. When I deleted the file and recreated it using the default font, it worked.
For info. only folks. I wonder if the control characters surrounding the new font somehow threw it off.
