where do you set the variable "m" ?

Yeah and these too:

return n
local n=menue(options)

Why are you returning n?

What function is menue?

[UltimateLP]

OK my program is working now, thanks! But now theres another problem! When I select the first menupoint and type in the server id, it asks for the nickname, right so far! But when I type in anything I will be ported to the chat screen and cannot type in anything, hes not listening on my event!

I am not going to download a file to solve your problem. Either put it on Pastebin or put it on the forums with ['CODE']['/CODE'] tags.

I'm not sure what you're trying to do after you open your wifi but here's a fixed part of the menu, and the reading of server ID and nickname.

And why did you not use read() to read the server ID and nickname?

OK, that works fine, but I can´t type in my message under the "------------------------------------------------"

Read what I said in my post.. I don't know what you're trying to do then so I didn't change anything there

[UltimateLP]

The user should enter a message, after the entry of server id and nickname! Under the lines, the user enters a message which will sended to the server, and here it will be sendet to all clients, a working chat =)

[remiX]

It's not letting you type because of this code, not sure what it's doing...

    -- Funktion "draw"
    while true do
        sleep( 0 )
        cBlinkT = cBlinkT + 1
        if cBlinkT == 5 then
            if cBlink == "" then
                cBlink = "_"
            else
                cBlink = ""
            end
            cBlinkT = 0
        end
        term.clear()
        term.setCursorPos(1, 1)
        local calch = h - 4
        for x=table.getn( tChatHistory ) - calch,table.getn( tChatHistory ) do
            if tChatHistory[x] ~= nil then
                write( tChatHistory[x] )
            end
        end
        term.setCursorPos( 1, h - 1 )
        write( "> "..cInput..cBlink )
        term.setCursorPos( 1, h - 2 )
        write( sBars )
    end

[UltimateLP]

It writes the GUI for the chat surface, the lines, and the ">"! But when I take out this function, it not shows the chat...

[Lyqyd]

Either make your "funktion"s into actual functions and use the parallel call, or merge them into a single event-based loop and remove the parallel call. Right now, you enter the draw "funktion" but never leave it, so your code stays there the whole time. Of course it doesn't care about key presses.

[UltimateLP]

Sorry, im german, thats about this "funktion"s And how can I leave this function?

[AngelMalus]

Seems like you are trying to run 2 processes at the same time. Your "FUNKTION" and the user Input. What Lua Liquidator suggests is to use the Parallel API and run 2 functions at the same time.

function1 = function()
print (rednet.receive())
end
function2 = function()
rednet.broadcast (read())
end
parallel.waitForAny (function1, function2)

[UltimateLP]

OK, but Im a noob, so can you place it in the script?

Lua Liquidator is his title, his name is Lyqyd.

I merged your key and receive 'functions' and put in the parallel:

A lot of errors will pop up because:

You're using 'tChatHistory as a table, you but never define it,

cBlinkT is never defined either

.. There are probably more

[UltimateLP]

And how to define the table?

[remiX]

If you do not know how to define a table, then you should go through the LUA manual and some tutorials in the tutorials sections and browse through and teach yourself. Then try the code again.

But anyway defining a table:

t_table = {}

[UltimateLP]

Guys, can you not give my a finish script that works?

[remiX]

Post the current code you have now and tell us your errors and i'll help you.
