Why isn't this working, did i do the TeamColor part wrong?

So this is my raygun script I have been working on. It has been working wonderfully until I had to make it so that they can't kill teammates. It just doesn't shoot at all. nothing shows up in output, and no errors pop up. What am I doing wrong? Sorry its a little disorderly.

tool.Equipped:connect(function(mouse)
    --store the character of the person using the tool
    user = tool.Parent 

    --when the left mouse button is clicked
    mouse.Button1Down:connect(function()
    if d == false then
        d = true

        --make and do a hit test along the ray
        local ray = Ray.new(tool.Tip.CFrame.p, (mouse.Hit.p - tool.Tip.CFrame.p).unit*300)
        local hit, position = game.Workspace:FindPartOnRay(ray, user)
 local player = Game.Players.LocalPlayer
-----------------------------------------------------------------------------------------------------------
        local humanoid = hit and hit.Parent and hit.Parent:FindFirstChild("Humanoid")
       opponent = game.Players:FindFirstChild(hit.Parent.Name)
 if humanoid and humanoid.Health > 0 and hit.Parent ~= nil and game.Players:FindFirstChild(hit.Parent.Name) ~= nil and opponent.TeamColor ~= script.Parent.creator.Value.TeamColor then
---------------------------------------------------------------------------------------------------recently added part
            humanoid.Health = humanoid.Health - damage
player.PlayerGui.Storage.Value = player.PlayerGui.Storage.Value + damage/2

        --draw the ray
        local distance = (position - tool.Tip.CFrame.p).magnitude
        local rayPart = Instance.new("Part", user)
        rayPart.Name          = "RayPart"
        rayPart.BrickColor    = BrickColor.new("Bright green")
        rayPart.Transparency  = 0.5
        rayPart.Anchored      = true
        rayPart.CanCollide    = false
        rayPart.TopSurface    = Enum.SurfaceType.Smooth
        rayPart.BottomSurface = Enum.SurfaceType.Smooth
        rayPart.formFactor    = Enum.FormFactor.Custom
        rayPart.Size          = Vector3.new(0.2, 0.2, distance)
        rayPart.CFrame        = CFrame.new(position, tool.Tip.CFrame.p) * CFrame.new(0, 0, -distance/2)

        --add it to debris so it disappears after 0.1 seconds
        game.Debris:AddItem(rayPart, 0.1)
wait(1)
d = false
end
end
end)
