Thanks so much for the reply!

Now I've advanced to the final part of the script, which was to come up with a way to have controllers be created and then set as parents of the locators. I've figured out how to do the parenting with the joints and the locators, since I can do it in the same loop - but since I want to give the user freedom to move the controls around before they're parented (by breaking this procedure and having a button the user can press once they're done rearranging which would call the "parenting" procedure), I can't really approach it the same way.
Is there any way to "save" the selections of two separate string arrays, and then have the corresponding locator and control names be matched?
I'm not even quite sure how to start tackling this one.
Thanks again!
