bios:206: '=' expected ?

Just need some help with this code!

It says on line 31 it's expecting '=' but i can't understand why?

Heres the code:

local clear = "clear"
local mbpro = 15

term.clear()
term.setCursorPos(1,1)
print("Genius Help")
print("Waiting for entry:")

function displaymsg()

if id == mbpro then

print("Help needed at: MacBook Pro ("..id..")")
print("Type clear to clear: ")
write(">")
input = read()
if input ~= clear then
print("Hmm, that wasn't one of the options!")
sleep(2)
displaymsg()
end

end 

end

rednet.open("right")
id, msg = rednet.receive()
rednet.close

displaymsg()
os.reboot()

Thank you very much, really appreciate it!! :D/>

Change:

rednet.close

To:

rednet.close()

*Brain fried*

Thank you!! :D/>
