How to teleport if integer = 0?

Hello , I would like to know how to teleport my character if a integer is equal to 0 .
So I have made collectibles in the game , those collectibles are with an integer and I would like to be teleported if this I lost the collectibles ( they are frag grenade , so if I throw 5 grenades I want to be teleported )

Additionally, OnThrowGrenade could be instigated by a [delegate][2].
Edit: I saw that you’re using the level blueprint to do this action. I would suggest against this as it can create some unnecessary problems. You should be able to transfer this segment to the character blueprint as it belongs there logically.
