Ok, PhoenixPower. You win. that did the trick.

So, the take aways from this lesson, for me, we're incomplete understanding of how and when data was being returned. A less than ideal mock up of the code for testing. And, chasing down the wrong issue to solve the problem.

Below, I have corrected the issues and all is working as intended. Thanks so much for all the help. I really appreciate it.

FWIW this button is what helps me escape long dungeons without running back to the entrance (Transmog Farmer Here). Not a new concept, but I like to be in control of my own tools.

Thanks again for all the help, everyone. I sincerely do appreciate it.
