Hi Dennis,

It seems that a tool in your history is producing parameters that aren't amenable to building a workflow. To help you, we need more information/help:

What tools are you using in this history? Can you try creating histories with a subset of tools in order to identify the problematic tool? Alternatively, you could recreate the history on our main server ( http://main.g2.bx.psu.edu/ ) and then, assuming you run into the same problem, share it with me.

Thanks,
J.
