Thanks for the reply. I should have given more info though. The instance names of the buttons can not be numbered in an ordered way. They will be named as numbers, but the sequence could jump from 3 to 7 to 23. Also, because there may anywhere from 5 to 500 buttons, I will not know the number of instances in the movie. I was hoping to hear that there is a buttons collection or something similar to loop through.
How are the button instance names generated? What you could do is push the instance names into an array which is essentially your "buttons collection." From there you can loop through the array and apply whatever functionality you need.
The instance names are hardcoded by hand, as each button instance is placed on the movie manually. I do not want to count the number of buttons placed on the movie as I do this, because I will be running my loop from another container movie that will have to loop through however many buttons are on the movie that I load. The movies that I will be loading will have no set number of buttons that I need to loop through.
