Thanks I will try that out. I have the name picker set up on a different page and it works perfectly. In fact, I have a field on this same form that pushes a full update on change (to any value, not anything specific). When I do that, suddenly the name pickers start working. Seems like the initial page load would set any parameter that a full update would set as well so, that's kind of a strange behavior. I may just have to rebuild the page and see if I can get it working without the error.
