I had to make a few minor changes to your example to type define the XML during the function, but otherwise the following WORKS perfectly! Can also, as a result, use dot notation to access individual elements / attributes for comboBoxes within components.
I think the biggest stumbling block for me is to get a complete grasp on the syntax for different UI elements and XML referencing the proper elements. Thanks for your help Tracy!
