I have a form with 5 dropdowns (First Choice, Second Choice, etc). Each drop-down has the same 5 items listed in it (Item 1, item 2, etc.) The end user will use this to select their preference from among the 5 items (their first choice, second choice, etc.)

Is there any way to verify that the user doesn't select the same item twice? In other words, if the user selects item 1 in the drop down "First Choice" is there any way to ensure that they can't select Item 1 again in the dropdown "Second Choice"?

By the way, I'm using RSForm Pro 1.4.0 R44 for Joomla 1.5 if that makes a difference. Thank you!

I have exactly the same issue. If anyone can help.

From RSJoomla support:

This could be achieved, but it will require custom scripting. One option would be to add a validation script in the "Scripts called on form process" that will make sure that the items from your 5 fields are different. You can use the $invalid variable in order to trigger a validation error if a duplicate is found, an example on this topic can be found here:
