Hello all,

I'm with this error for hours, and after a several sheach in this forum I can't find my anwser...Is there many sugestions but none is the correct to my problem... I've tried everything and it still doesn't work... The type of data it's ok for all fields I compare that twice, I can't resolve this issue... Anyone can help me on this?

Thank you,

What functions or logic are you using within the transformer that will require a numeric string? Any columns which are referenced by that logic will need the strings to contain nothing but digits and appropriate numeric-related "punctuation" (signs, decimal points, etc.). Num() is a function that distinctly does not like leading spaces or empty strings.
