Do a number of times

[TuXsOrDs]

I am looking for a BP node that will do a thing a number of times. like a wave spawns, I want it to do something a number of times in which I can control from an array

I have an array, and it is an integer and I want something to repeat a number of times based on the index I tell it to use. by form of doing this is wrong and I cant find any way of fixing this.
