I'm having a problem with Model Builder. I created a model from a series of tools. If I run the model from Model Builder editor, it runs fine. However, if I run the process from the "Open" option (where it opens up like an ArcToolbox tool), it does not run properly. Any idea of what may be going wrong? Running from model builder is not an option as I'm trying to build a tool that takes in parameters. Any insight would be great!
