I have arcView 9.3.1
Does anyone know how to calculate quotient in model builder using "Field Calculator"? This seems to be simple, but I have problem. Expression which i want to calculate looks like this:

field - [area 1] / [field - area 2]

When i try calculate this expression I get an error: "Error running VBA code: user interrupt".

Please, help me solve this problem. I will be grateful.
