The Alternate states worked correctly, but I am having trouble creating the post button. I copied the existing list box to create the alternate state from the Field Normalizedname1. I created two list boxes both pulling from that field called Target List and Posting list. Posting list is the one I set as an alternate state. I tried to create a Select in Field action and a Toggle select action using the expression:
If you're using QV11 then you can use alternate states. See here for a demo. The demo uses more than one listbox to select from, but the idea is the same: select values in a field and add them to a list and then later use that list for a selection. In your case you should only need two alternates states and two listboxes.
