Hi Terry,
Interesting project!
BTW, the runtime variable value limit is 10,240 bytes (10KB) when using the "Set VariableEx..." script function. This is not enough in your specific case?
I have created a demo project for you:

See attached screenshots. It "re-loads" the combo box with new values.
Does this help?
