Piston door code help

I have a Problem with my program for an disk-protected piston-door(has an and-gate)
The program should give out a redstone signal if the disc is in the drive
Code:
————————————
repeat
print("Insert Disk")
shell.run("clear")
until disk.getLabel("front") == "Password"
print("Disk is inserted!!!")
rs.setOutput("bottom", true)
sleep(2)
rs.setOutput("bottom", false)
sleep(0.2)
shell.run("clear")
end
shell.run("Pistons")
—————————–

Error:
Every time I type startup in the Console it jumps to a new line and says 204
If I repeat that "command" it says 204204 and so on…

Please help me… :(/>

Use an infinite loop for this-

while true do
Do stuff
End

why clear after print?

Also, put a sleep in the until loop, or use os.pullEvent

Ok Thanks ;)/>
