Function Not Being Called

[Muntrax]

Ok. Check where you set the reference

[1-1.u.m.a.n]

I tried that but the problem seems to be in the reference because when I use a cast node, the cast fails.

Try plugging AutoFire directly to the timer.
And from "Pressed" you executed

InputAction Fire > AutoFire (Call)

AutoFire Event > Set Timer by event> SetTimerHandleVariable> PrintString"Should Fire"> Fire function"

[1-1.u.m.a.n]

The player character is supposed to call a function on the gun but is doesn't? I've done some testing and it seems to be a problem with the casting but I don't know what.
