I'm having some problems adapting a few models inherited by me from a colleague.
Inside this model, we attempt to calculate summary statistics, but the model can't find the field that it needs to use. The Model Builder refuses to show it to me, despite the fact that the Feature Class in this calculation possesses the field in question.
Has anyone seen weird problems like this one? The original model was for 9.3 and I'm rebuilding it in 9.3.1. Any pitfalls I'm not aware?
