True, post is old, but it does what I was looking for. My problem is that I cannot create something that works the same. I can copy of course and it works fine, but not from scratch. If somebody stumbles across this can you explain how the "+add a new one..." portion of this works? How can I create it from scratch?

That section just makes the string control and ok buttons visible when the "+add a new one..." is selected.  It is just using a property node to get the available strings from the listbox and then array size to get the number of elements in the listbox.  If the final value is selected, the other controls become visible (again, just property nodes to the other controls).  What part of it do you not understand how to create?

Must be the day I am having. I have created 4 versions now and all work as they should. I don't know why it would not work the first few times I tried it. What would happen is when I clicked on the last item the string control and OK boolean would pop up, the immediately go invisible again as if another action had occured. Not sure why that was happening though. Thanks for the quick response though.
