Textboxes on different frames from one array

I have a concentration style game where each thing pulls from a different frame. That works fine.

Rather than constantly changing each frame I want to have an array one the first frame and have each textbox be populated from an index. I don’t even care about frame one being from index one, at the moment I can’t even get any textbox to show anything from the array.

Currently the frames are in a MC which is on the stage. I can put the array anywhere.

I hope this makes sense.
