My formula give's an error:
string length is less than 0 or no number (this is translated so it can be not the exact English error.
This error is given when I run a report, if I check the formula and his syntax it's ok. But when I want to display a print preview I get that error.
The formula is called add_formula1# and the code is:
Mid({@formula1#},1,(InStr({@formula1#},":") ))
Wo can help me solving this problem?
