all of the ends are there because i have 7 programs in one program so i need all of those

You need to save the received id and message to use them:

local id, msg = rednet.receive()
print("Message sent from: ", id)
print(msg)

Also, you don't have to do rednet.close before rednet.open.

Your formatting is weird.
