Hi all, I'm receiving this message when I try to use field calculator in the attribute table to do this operation: [PERCENT_A] /10* [Class_A_ne] + [PERCENT_B]/10* [Class_B_ne]+ [PERCENT_C]/10* [Class_C_ne] Can anyone help me in this matter?
Check the Results window (see figure) for specific error message. It usually help to determine the problem. [ATTACH=CONFIG]12755[/ATTACH]
The most common error in calculation is using text values instead of numeric. If it's the case try using Cint([field_name]) or Cdbl([field_name]) for converting respectively integer type values and double type values from text.
