My intro wont work!

Here's the script in a code block.

I'll assume you declared all the variables. All edits are commented on in the script. I hope this helps.

wait (2)
--[[for i = 1, 10 do        this is the old loop
    trans = 1/10
    trans = 1 - trans
    script.Parent.BG.BackgroundTransparency = trans
    wait (.1)
end
--]]

for i = 10, 0, -.1      --My version of the loop

    wait()
end

        wait (3)

            wait (.2)

            x = Instance.new("IntValue" , script.Parent.Parent.Parent)
            x.Name = "WentThroughCutscene"
            script.Parent:remove()
        end
    end
end)

This is the script you asked for on ROBLOX from "The Football Coach"....It'll take lots of editing to match your game set but have fun!
