Ok, thanks for your feedback. I tried using the GetRef function as suggested, but was unable to get this to call my event sub and I’m not sure I have the time in my project plan required to delvelop a com enabled solution to accomodate this need.

This is unfortunate, but I guess I can achieve the same functionality using the limited Utilities.NewControlBoxDialog and either use a button to force an event or use chained dialogs for presenting required fields dependant on dynamic field values. A very outdated UI methodology but functional none the less.

Thank you for your time looking into this, much appreciated.
