TerminalGlasses/Bridge ProgrM

I'm having issues with this pastebin code*so i didnt make it cause i didnt wanna take till next year* and i have the error "temp-update:14: attempt to index ? (a nil value)" my question is whats causing this
The line of code it "clientB.clear()"
Any help would be appreciated, Thanks
*id like to just add this is a program that lets you send messages to other players on the same network with the command $$"text"*

Please post the code, or a link to the code on pastebin.

As Lyqyd said, the code would be helpful. From the error and the line you *say* is causing the issue, clientB is not a table… It's nil (ei not defined).

The pastebin i got it from is at http://pastebin.com/zfmzr5vH

My mistake, you will have to run that program then right after you run it terminate it then open the file

The code is looking for (and failing to find) a glasses bridge besides the computer running it. For whatever reason, it's rigged up in such a way that it can't detect the block via a modem - it needs to be right next to your system.
