Check for certain armor equipped not working. [FIXED]

I am trying to make an armor set where if you if you have certain armor equipped it will remove a potion effect and deal damage to the armor.

Here what I have now, but it's not working:

If] [Get item from armor slot [3] of [Event/target entity] = Helmet] [AND] [Get item from armor slot [2] of [Event/target entity] = Chestplate] [AND] [Get item from armor slot [1] of [Event/target entity] = Leggings] [AND] [Get item from armor slot [0] of [Event/target entity] = Boots]

Do] [Remove specific potion effect from [Event/target entity] type [Custom Effect]]

[Deal [1] damage to [Provided itemstack]]

Also this procedure is put on tick event for all the armor pieces.
