Help with getting timer script to work, somehow using else instead of end?

Hello, I am making a timer script that counts in Hours, Minutes, and Seconds, but at line 13 it always says "Expected 'end' (to close 'else' at line 12'), got else. No matter how many "end"s I put, the problem is never fixed. Here is the LocalScript:

function Count()
    wait(1)
    Seconds = Seconds - 1
    if Seconds == 0 then
        Minutes = Minutes - 1
        if Minutes == 0 then
            Hours = Hours - 1
            end
    end
    if Hours > 9 then
    if Minutes > 9 then
    if Seconds > 9 then
    script.Parent.Parent.Timer.Text = Hours..":"..Minutes..":"..Seconds
    else
    else
        else
    if Minutes > 9 then
    if Seconds > 9 then
    script.Parent.Parent.Timer.Text = "0"..Hours..":"..Minutes..":"..Seconds
else
    else
    if Seconds > 9 then
    script.Parent.Parent.Timer.Text = "0"..Hours..":0"..Minutes..":"..Seconds
    else
    script.Parent.Parent.Timer.Text = "0"..Hours..":0"..Minutes..":0"..Seconds
