Why can't i get the 'Actor Has Tag' node to work in my character blueprint?

I am making a system where a different version of the same character blueprint will be possessed every time a certain actor overlaps a sphere component within the character blueprint.

The possession works fine when I allow any actor to trigger it but when I try to use the ‘Actor Has Tag’ node to limit it to just one actor it stops working entirely. Here’s a screenshot of how I have it set up within the character blueprint at the moment:

Any help would be appreciated, thanks.

You need to connect the pin “Other Actor” to the target from “actor has tag”

Oh of course! Thanks.
