How do I add delay inside my nested loop?

I'm playing an animation on some cards in my project. Using nested loop I fetch the values and then play animation named as "Yes" to play on that specific card. Here's my event sheet screen shot for that even:

What I want is to add some delay after 1st inner loop iterations completed so that the next animation on cards run after some 2-3 seconds delay. I've already used wait & every X seconds inside these loops but not getting the result I want. Anyone please help?

Use something like "wait 1 * loopindex seconds" - this will ensure that for each loopindex, the wait is increased. Just be aware that this can cause some weird side-effects if you end up with overlapping events happening at the same time. So test as you go! :)

Dont't forget to compare value whether an iteration being in the tick. I assume the "columind" is a kind of counter so you know where the loop being at.
