How do I properly use for each loop?

So here I am trying to call unblock function for any unblock object that is both special and ID 2.

I believe the issue is here, can anyone identify what it is?

By ID do you mean the "Instance" variable value, or IID?

It's better to move conditions 3 and 4 before the For Each, this way the loop will process only the picked number of instances, not all of them:

Trigger ID=2
Unblock type="special"
Unblock instance="2"
For Each Unblock
