Event 4 is running on every tick, which is not great.

Select event 3 and press X to add an "Else" condition - you should re-initialize permutation table there.

Also, I made a mistake in my screenshot - "Add 1" action should go after the "Set text".

I'm trying to understand how to have two lists feed into one text box - both triggered by the same action -* and to repeat both forever even if they are of different lengths*.

So a three item list cycles twice during the same time as a six item list (but they wouldn't need to be multiples/factors of each other. Each list could be any number of items).

Here's my perhaps closest attempt.

So in this example project file above (with two lists: [a,b,c] and [1,2,3,4,5,6]), six button clicks would return something like:

a 3

c 4

b 1

c 6

a 5

b 2

... and the next six different, forever.

I've spent about six hours so far and I haven't gotten it so I'm going to reach out. Many thanks for any assistance! I really appreciate it.
