Help needed sending a UI activex reference back to teststand

Hi again folks, next conundrum.

I have inherited a large user test GUI that besides other things, sets up an active x control to write to a database, all works fine within the GUI.

However I need to write to this same database reference, from within the teststand script that's being run.

Effectively I need to pass the COM reference generated by the GUI, to a variable in the script. So that when the script runs it's VI to write to the database, it can pick up the reference that's already been generated by the GUI.

I have tried making use of this tutorial to accomplish this but it's not worked so far: https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000kHD9SAM&l=en-GB

Attached are some screenshots.

Please help!

Thanks, Tom
