RESOLVED: How do I work with multiple instances individually?

I just can't figure this out. I'm trying to change individual time fields. I'm requiring the user to double-click on the time they want to change. I don't want them to be able to double-click on another time while the first time is being edited. The screenshot is the code that I have now. I've been playing around with this for awhile now with no success. I have deleted most of the other code to focus on this part because if I can't do this, I can't do the rest.

To lock out all instances you can take a more general approach, so when you click on the object, set a global variable to 1. When the editing bit has finished, set the global variable to 0. Then on the initial click object logic add a condition that the global variable must be 0. The change to 1 locks out any more clicks.

I'll give that a try. Thank you for your reply!

It worked perfectly. Thanks again!
