I'm trying to using this formula in the field calc but keep getting an error.
Sqr(([Field1]^2) - ([Field]^2))
Any tips would be greatly appreciated!
Make sure ([Field1]^2) - ([Field]^2) value is not negative in any case.
Some questions to help clarify the issue:
1. What error do you get?
2. In the Field Calculator, did you select the VBScript Parser or the Python Parser?
3. Also, which version of ArcGIS are you using?

That did it, thank you!
