Thank you guys, but I understand that. My problem is how to do that with an expression.
How to get the right instance index ID of an object in an expression.
Example: I have three instances of the same object in the layout. And it have a variable called IsFull. So, to show it to me:
EVERYTICK - SET TEXT TO - "Variable IsFull: "&Object.IsFull
^ But I want that information from the 3 instances of the object that I have in layout, and not just from the "0" instance.
