Radio Button Matrix

Radio buttons allow you to choose one of several options. This script allows a choice of one option from each row and each column of a matrix of options. Selecting a radio button will remove any other entries in the same row or column.

You could use this script to order a group of items:

Rate the following in order of importance to you:  

1st 2nd 3rd 4th 5th
Code that validates  

The script will also work for non-square matrices where there are fewer columns than rows. For example, you could remove the 4th and fifth columns above and request only the top three choices.
