Get stuck between timeline and world location.

I’m new with unreal engine 4. I have already watched many of tutorial’s. I’m trying to make door which I could open by keypress and then they will close automaticly behind me. I have tried to use “reverse” on timeline but this caused a delay reversed animation so I can’t sync sound effect of closing doors. Then I have used second timeline and this solved problem with audio but it caused problem when I try to open a door second time, nothing happen. I understand the problem is with “getworldlocation” and it variable, but I have no clue how to properly use it. So please, help:D
This is my blueprint:


DCD overlap give me info if door is open and close it if its true.
