How do i make a tutorial gui with a button that has a next button?

hello there!! im trying to make a gui so that when you click on the next button another text shows up. here is the code for the next button:

x=1
script.Parent.MouseButton1Click:Connect(function (ueeeee)
    if x==1 then
        script.Parent.Parent.Parent.Buttons.zero.Visible=false--"zero is a tutorial label, all of them are numbers like this
        script.Parent.Parent.Parent.Buttons.one.Visible=true
        x=x+1
    if x==2 then
        script.Parent.Parent.Parent.Buttons.one.Visible=false
        script.Parent.Parent.Parent.Buttons.two.Visible=true
            x=x+1
    if x==3 then
        script.Parent.Parent.Parent.Buttons.two.Visible=false
        script.Parent.Parent.Parent.Buttons.three.Visible=true
            x=x+1
end
