I'm trying to run a rather lengthy model (built in ArcGIS 9.3.1) in ArcGIS 10.1 and I'm recieving an error on a Calculate Field tool. The error is -
Type mismatch: 'iif'.
This error is refering to an expression in the tool:
iif(IsNull( [PID] ) ,NA,[PID]).
I tried "if" instead of "iif" but then recieved a generic error.
I never had this issue when running the model in 9.3.1. I'm not sure what to do here. Any suggestions?
