Correct....thats my issue. And yes I've tried the case to where could wait until the initial tool runs (Strip Map Index Features), stops running and produces "output", open another tool (Make feature layer), then use the "output" as input to the MFL...but that seems like so many more extra steps for the user (building this for a customer -- a not so computer savy customer), wouldn't you agree>? lol
I'll try the pre-condition idea and see where it takes me, as well as continuing to research. I appreciate your help and ideas, Thanks!
