First, I'm using Arc10, but calling

import arcgisscripting
gp = arcgisscripting.create(9.3)

because I am making a script for other users.

I get the following error when I try to use a codeblock/expression to calculate a field.

ERROR 000539: Error running expression: autoIncrement(gp.GetParameterAsText(2),gp.GetParameterAsText(3)) <type 'exceptions.NameError'>: name 'gp' is not defined
Failed to execute (CalculateField).

It seems that I can't pass in variables to my calc field code.
gp.CalculateField_management(FCls30, IDPK, expression, "PYTHON", codeblock)


expression = "autoIncrement(gp.GetParameterAsText(2),gp.GetParameterAsText(3))"

If I pass in a string for each argument, then no problems.

Please help.
