Model Builder error.

Discussion created by briancoward on Sep 12, 2011
I'm working in ArcCatalog 9.3.1 (Build 3000) with model builder and I have Union in the model that gives me this error:

Executing (Union (3)): Union "COWS_waterside_Layer #;'F:\CD Engineering & Inspections\MAPPING\CITY_DATA\DEPARTMENTS\FACILITIES_DEVELOPMENT\REVISIONS\41164_SOUTHPORT_EIP\Second_Analysis\Real_Estate_Analysis.mdb\scratch\CMA_1_20ft_PARUNILEV' #" "F:\CD Engineering & Inspections\MAPPING\CITY_DATA\DEPARTMENTS\FACILITIES_DEVELOPMENT\REVISIONS\41164_SOUTHPORT_EIP\Second_Analysis\Real_Estate_Analysis.mdb\scratch\CMA_1_20ft_UNION" ALL # GAPS

I've been able to union these two features in ArcMap so I know the features are good. I've tried moving my personal geodatabase to my local C: and shortening the feature names but I haven't had any luck getting the union to run in model builder. Any thoughts?
