Melee tool not working on a certain line?

INFORMATION: I was working on a melee tool for a while now, everything was going smoothly until I wanted to make it where if the player jumps and presses q in a certain time they will do an overhead attack that will do stuff later on, but while scripting it, nothing prints, can I get some help?

PROBLEM: (What I presume) The script gets to a certain point and the script and freezes/stops and does not print anything.

SCRIPT:

-- change variable when player jumps 
character.Humanoid.Jumping:Connect(function()
    jumping = true
end)

uis.InputBegan:Connect(function(input)
    if input.KeyCode == Enum.KeyCode.Q then
        if toolEquipped == false then return end;
        if kicking or guarding or usingSpeical == true then return end;
        if not punching then
            punching = true

            -- overhead
            if jumping == true then
                if tick()-timer < 0.15 then
                    print("overhead")
                    wait(0.5)
                    punching = false
                end
                timer = tick()

            else
                if tick()-timer > 2 then
                    punchAnimation = 0
                end
                timer = tick()

                punchAnimation = punchAnimation + 1
                local ActionAnimation = character.Humanoid:LoadAnimation(replicatedStorage.Animations["MeleePunch"..punchAnimation])
                ActionAnimation:Play()
                actions.Punch:InvokeServer(punchAnimation)

                if punchAnimation >= 2 then
                    punchAnimation = 0
                end
            end
        end)

Any help would be greatly appreciated!
