[ERROR] Bag Argument!

I'm trying to make a turtle controller but I cant find my error!

'134shell:65: bad argument: string exspected, got nil.

Heres the code…

write('Please enter the bot's id: ')
bot = tonumber(read()) – the ID of the turtle
shell.run('clear') –clear the screen
mode = 0 – set the mode to dig
rednet.open('right') – open wifi port
while true do – start infinite loop
event, key = os.pullEvent() – wait for input
shell.run('clear') – clear the screen again :P/>/>
if key == 's' then –if the s button is pressed
rednet.send(bot, 'backward')– send message for down button
print('Backward') – write on the screen
end
if key == 'a' then – left
rednet.send(bot, 'left')
print('Left')
end
if key == 'w' then –up
rednet.send(bot, 'forward')
print('Forward')
end
if key == 'd' then – right
rednet.send(bot, 'right')
print('Right')
end
if key == 200 then
rednet.send(bot, 'up')
print('Up')
end
if key == 208 then
rednet.send(bot, 'down')
print('Down')
end
if key == ' ' then –if the key is the spacebar
if mode == 0 then – if on digmode
rednet.send(bot, 'dig') – send message to dig
print('Dig') – write it
elseif mode == 1 then – if on placemode
rednet.send(bot, 'place') – send message to place block
print('Place') –write
end
end
if key == 203 then –if the key is left
mode = 0 – set to digmode
print('Dig mode selected.') –write it
end
if key == 205 then – if right
mode = 1 – set to placemode
print('Place mode selected.') –write
end
if key == 29 then –if the left ctrl is pressed
rednet.send(bot, 'rs') – send message to enable redstone
print('Redstone activated.')– write
end
end

Please help me get a fix!
Edit: Were it said enter ids, i entered the correct ones.

Its due to line 33. The space bar is key # 57 not ' '.

I would also change your if statements. Instead of doing multiple if's to check the 1 input do 1 if with some elseif's. It will work better in the long run. You can add an and statement to check your modes as well.

Example

if key == 57 and mode == 0 then --if the key is the spacebar and if on digmode
  rednet.send(bot, 'dig') -- send message to dig
  print('Dig') -- write it
elseif key == 57 and mode == 1 then -- if on placemode
  rednet.send(bot, 'place') -- send message to place block
  print('Place') --write
elseif key == 203 then --if the key is left
  mode = 0 -- set to digmode
  print('Dig mode selected.') --write it
end

I would also use double quotes " instead of singles '

Also if you want to check for say both wasd and the arrow keys use an or

if key == 30 or key == 203 then -- left arrow key or "a" key pressed

Here is a chart for the key codes http://www.minecraft.../wiki/Key_Codes

I did what you said but now it says

"bios:206: [string "startup"]:55: '<eof>' exspected"

I'm kinda a noob at this. It would be nice to know how to read these error codes.

my
guess based on what you have said is that you put a end after every elseif you only need one per IF not counting ElseIF's like his example. the <eof> error is telling you there ate too many end statements you need to pin where they are and remove them.

'134shell:65: bad argument: string exspected, got nil.

This means that instead of getting a string like the function expected it got nil or nothing.

"bios:206: [string "startup"]:55: '<eof>' exspected"

Is usually do to an extra or missing end somewhere in your code. Can I get a copy of the current updated code and I'll see if I can't find the error. The number in bold is the line of code that it is having a problem, it doesn't always mean that it is incorrect. But its a good place to start.

I'm realy a noob at this, how do I get my code off the computer?

Note: I didnt add any ends I just did what you said.

goto %appdata% if your on a windows machine. Then goto .minecraft/saves/worldname/computer/computer id number and the files should be there

also for future reference

I found out what was wrong. I was missing an end but now it says:

'134shell:65: bad argument: string exspected, got nil.

Also will I be able to get it off the computer on a multi player server?

Tils is frustrating :P/>/> If you have any codes that let you control turtles let me know, I'm done with this one!
