Is [FEMALE_POP] ever zero? If so you would get a runtime error dividing by zero.

Abdul_HameedKhorami1

No .[FEMALE_POP] is not zero !

Just thought I'd ask. I have shared your query to a more appropriate forum, maybe an ArcObjects programmer can help you out...

Can you copy & paste the expression from your code into ArcMap? Does it works?

I do not think you need the square brackets any more.

curtvprice

Mody, that's a good suggestion.

Square brackets [FIELD] are still used for VBScript expressions, for all data types.

Exclamation points: !FIELD! are used for Python expressions.

Note, you may want to explicitly set the parser (this defaults to VBScript, which will fail if the tool is run in 64 bit).

In arcGIS it works, maybe I am using wrong expression in my programming ? can you help me to write correct expression ?

mody_buchbinder

I hope GenderStr is double and not string. ArcMap will translate automatically but not the code

Abdul_HameedKhorami1

its its double!
