Literally how? I don't understand how Club Sanity, Club Insanity did this dancefloor?

Correct, you can keep them named whatever if you know how to utilize the table properly. I also suggest that you use frames or imagelabels and not textlabels.

I want to keep the same frames, not add more textlabels

How would I reference the rows, I’ve tried this script and it didn’t work.

Don’t need to have anything grouped up or call things in set up rows.
Just need to know the each square and location. From there you just script out effects.
Each square can turn into any color in any order depending on the script calling them.

Where is the script for this?

It’s in the frame where the textlabels are I don’t want anything grouped, named or anything I want everything named textlabel
