Montage Section Not Playing

Hey folks,

Just been wondering if anyone could be able to help me a bit with playing anim montage sections?
See, the issue I have is that montage section is not playing after the branch check. It’s a very simple setup, anim montage with 3 sections (attackStart, attackCharge and attack) and one bool controlled by button pres. But for some reason it never gets through the first branch check (isChargingAttack), which is simply controlled by the mouse button pressed/released (true when pressed, false when released). But for some reason it just won’t get past the check. I’m getting bit lost in there, stuck on this issue for 2 days now. Does anyone have any advice or ideas why it doesn’t work?
