Security Error on DS Form for wfwk.3

I have created a series of Design Studio versions of WFWK.3 (workflow trigger). Basically, I modified the form to default the service name and description, and removed the fields that were not required. All the forms work fine for me, but other users can see and use one of the forms, but get a Servlet Xpress error when they try to use the others (see attached). The xml files are identical except for the defaulted fields. The only other difference is security. I have full rights (under LAUA), and the other users have limited rights (under LS Security). The users can see and use WFWK.3 directly, and they can see and use one of the DS forms, but not the others. Our security folks are out of ideas. I have tried: - reindexing forms - changing prodline/changing back - IOS Cache Refresh I have attached 3 files: the error message received when selecting the bookmark, the DS form that works (wfwk3ltmint_supers.txt) and one of the DS forms that don't work (wfwk3ltmint_jobs.txt). I'm stumped on this one, and I'd appreciate any help I can get. Thanks!
