Youtube with dynamics components extension its not working

hi, im trying to make this blocks work, but i cant, youtube component works with dynamics components extension?

This is wrong method of creating dynamic

How would you do it? i dont know why its not working

You must create youtube player depending upon length of the list

Dont use for each items in the list,
Instead use
For each number From to by block

yes i know, i just was using that for the example
