this is close, when an SO is selected, it brings up the vendors, the problem is that if there are no call-ups against that vendor, it shows a space for it, but no the name. I think the problem is that this is a copy of the original section you made that I modified, but it's still getting some of this information from the Callup_DC, but it should be grabbing vendor names from the vendor DC, filtered by the SO selected.
