Outline one instance only

Hello friends, here is a simple c3p file

dropbox.com/s/jxrfoz2qg89ow73/Outline%20only%20one.c3p

There is a text box, and an instance of it. I am using the BetterOutline effect, and I want to be able to click on either piece of text, and have only the one I just clicked on show the outline. As it is they both stay outlined.

Many thanks for any assistance.

Two answers, two different methods :

Making use of the Pick All system condition:

Making use of the Functions feature:

Same result in the end.

Thank you, this is working. I don't understand how to do the second example, but I got the first one working.

TextUID is indeed a local variable.

Use the system action: "Set global/local variable value".
