Rednet Confusion

Ok so I have a computer and a turtle both with open modems but I cant get the rednet.broadcast("message") or rednet.send(63, "message") to work can anyone see what I have done wrong:





I did the rednet.receive(100) first before any commands on the computer but nothing shows on the turtle

Have you opened a rednet side? rednet.open("back") or whichever side

Yes, both modems are open. They are both on the right side and i know they are on because there is a red ring around them, any other surgestions?

Run the code inside the programs

Which would I run first? The turtle or the computer also i saw someone do it without programs on a tutorial like I was trying to do it so how come it dosnt work?

You run it on the turtle first since he needs to listen and then the sender needs to send. I'm not sure why your having trouble with the other way.
