I’m trying to automate some processing steps for several shapefiles that are contained within multiple subfolders. I am able to iterate through the subfolders, but the model won’t iterate through the shapefiles. The child data element doesn't refresh for the next iteration. So I get the error 000800. I've tried creating a submodel to iterate the shapefiles separately, but I can't get it to connect to the main model.

Is there a way to fix this or work around it?? I'm new to working with modelbuilder... any help would be greatly appreciated!

Are you using ArcGIS 10.1 SP1? If so, and you are open to ArcPy, then ArcPy.da.Walk would be my tool of choice to do this. –  PolyGeo Jul 4 '13 at 0:37
