What have i done wrong in this code?

what have i done wrong in this code?

os.pullEvent = os.pullEventRaw
print("Write Start When ready")
Start = read()
if Start == "9638" true then
print("Shutdown Starting")
rednet.open("back")
rednet.send(29, "SB Restarted")
print("Remove disk")
sleep(3)
os.reboot()
else
term.clear()
print("Order Support from here")
print("if your not a owner of MBP")
print("it costs 10 Coins")
rednet.open("back")
print("Name")
Name = read()
print("Problem")
Problem = read()
print("You will be Contacted soon!")
rednet.send(29, Name)
rednet.send(29, Problem)
rednet.send(29, "--------------------------------------------------")
rednet.open("back")
id, message = rednet.receive()
print(message)
sleep(5)
os.reboot
end

Well, you'll need to remove the true from this statement:

if Start == "9638" true then

Other than that, it looks like it should at least somewhat function.

Your last os.reboot() is missing the () at the end.

sleep(5)
os.reboot  <--- Here
end

I'd like to add that when you ask for help in AaP you need to be more specific, like.. what error code are you getting?
But you've already gotten some answers because it's pretty easy to spot the errors in your code.

Change this

os.reboot

to this

os.reboot()

and this

if Start == "9638" true then

to this

if Start == "9638" then
