Hey! I think I know the problem.
This part of your code is the most likely culprit.
You enter the return node immediately which will stop the function immediately once you hit it, meaning that every time you set that variable, you are only setting it to the first item in the array and then returning the function so it can never be set to anything else.
If you want every value you will need to either get the whole array to use from that function, or add an input of an index to pull which specific item you need. You can also just add a value to the return node and use that directly if you don’t need to save the variable for later.
Hope this helps
