Dropdown Lists - Remove item once it is selected

[Jasmine_SPAWAR]

Software: Adobe LiveCycle Designer ES 8.2

I created a form with four identical dropdown lists, containing the same list items.  What I want to do is somehow link these four dropdowns so that once I choose "Item A" from the first dropdown, it is removed from the others so it can't be chosen twice.  And if I choose "Item B" from the second dropdown, it is not available from the other dropdowns, and so on...

I believe I have to do some scripting to achieve this, but I am totally new at this, so any help even getting started would be appreciated.

Thanks in advance!

This isnot as easy as it sounds ......I created a sample some time ago. If you are new at coding you may have issues with this.
