CR12 - Formula editor, why do I get message "A field is required here"?

Question

In both cases below, I get the error "A field is required here".  How do I sum a text column that has numbers in it?
Sum(ToNumber({data.TextColumn}))
ToNumber(iif(isNumeric({data.TextColumn}),{outbound_bol_detail.weight},"0"))

Answer 1

Hi John,
Your if statement is a bit off.  Try doing it this way instead:
If NumericText ({data.TextColumn}) Then
    ToNumber ({outbound_bol_detail.weight})
Else 0;
Also, have a look in File | Report Options and turn on Convert NULL Values to Default.  It's possible you may have NULLs in the data that Crystal is having problems with. 
Good luck,
Brian
