Assigning Units with Variables

I haven't been triggering for a while, so I forgot how to properly assign units using the "For each For each (Integer A) from # to #, do (Actions)" with Variables.

The numbers are 1 to 12, and this is the trigger:

For each (Integer A) from 1 to 12, do (Actions)
Loop - Actions
Unit - Create 1 Portal for Player 1 (Red) at (Center of (Playable map area)) facing Default building facing degrees
Set sfx_portal[(Integer A)] = (Last created unit)

When I add the "Unit - Remove" action, it doesnt work.

Unit - Remove sfx_portal[(Integer A)] from the game

It creates the units, but doesnt remove them. How do you properly assign them?

Did you add the remove function to the loop or is it outside it? If it's somewhere else then you need to create another loop (from 1 to 12) and there you should add the remove function.
If it's inside at the end of the loop then I donno :/
