Scratch

So im trying to make it so that when my Sprite goes to costume 6, the game waits 2 seconds, then stops as if it was a Game Over. But it seems to go to costume 7 (Power Up Costume) and continue on like nothing happened. Heres the Script:

when gf clicked
set [speed] to [-10]
set [Damage Taken] to [0]
set [Score] to [0]
switch to costume [costume1]
if on edge, bounce
go to x: (-202) y: (0)
set x to (-202)
show
if <(costume #)=[6]>
 wait (2) secs
 hide
 broadcast [end]
end

when I receive [HP]
 if <(costume #)=[1]>
  switch to costume [costume 7]
end
 if <(costume #)=[2]>
  switch to costume [costume 1]
end
 if <(costume #)=[3]>
  switch to costume [costume 2]
end
 if <(costume #)=[4]>
  switch to costume [costume 3]
end
 if <(costume #)=[5]>
  switch to costume [costume 4]
end

when I receive [Hit]
next costume

when I receive [End]
wait (0.1) secs
Stop all
