How do I display initial value of popup menu at GUI launch?

I am able to call up whatever value is shown after an initial selection, but the default value is still not getting used at launch. I have boiled this down to a much simpler GUI that basically displays whatever selection you have. What I would like to be able to do is have this display 'A' when the program launches, then A, B, C or D once they are selected from the popup menu.

See attached help.m file.

What am I piece of this puzzle am I missing?

You forgot to attach your file.

You should just need to set the 'String' to { 'A', 'B', 'C', 'D' } and the 'Value' to 1 on creating your popup and that will show 'A' when it initialises.
