On edit script issue

On edit script issue

Hi there,

I'm recently getting an error that has not happened before.

When I edit an existing entry and try to add a new Subform row, I get something along the lines of:

"
Error in executing On Add Row script of XXXX.
      Error.
            Error in executing Set Variable task. Unable to update variable XXX.
                  Error evaluating NUMERIC expression:
                        ...
"

Adding new entries does not produce this error.

I suspect this might have to do with a recent update since it was working just fine over the past year. Please help.

Thanks,
Kyle
