@Lenooox two lines need to be changed to remove this error.
You will find them around line 13.
Find this:

    if ($numtok(%serv1 %chan1 %serv2 %chan2,32) == 4) { $input(Setup Complete.Remember to turn the power on!,,Script 1.0 by ChiefDean) }
    else { $input(Critical Setup Error! Please return to Relay Setup and Start over!,,Script 1.0 by ChiefDean) }

Replace with this:

    if ($numtok(%serv1 %chan1 %serv2 %chan2,32) == 4) { noop $input(Setup Complete.Remember to turn the power on!,,Script 1.0 by ChiefDean) }
    else { noop $input(Critical Setup Error! Please return to Relay Setup and Start over!,,Script 1.0 by ChiefDean) }

This error shouldn't effect the script Lenooox. It's just a one time error when you clicked on the $input box. If you had clicked "cancel" instead of "ok", it would have said $false instead of $true. It has nothing to do with the functionality of the script, it's just a check to see if you filled in all of the boxes.

If this script isn't working for you, make sure that you have filled in all for boxes properly.
Rules:
1) The bot must be on both channel one - server one and channel two server two.(The script will do nothing otherwise.
2) In order to see the results, a second client must be on both server/channels and this client must type something on channel one to see the it on server two.
3) The network names must be typed exactly when you enter them in setup.(type //echo -a $network -- to see the exact name of the network you are on.

@ChiefDean You should replace the word Server with Network, as they have two different meanings and Server is not applicable here.
