Sending a table via rednet doesn't work

Hello, i create a little program for my friend for his house to monitorize his energy and input lava and other thing. I make 2 programs (sender to main computer, main computer) and all is going fine, and when i sending a table via rednet and the computer receive it, but the computer that its receiving it, is thinking that isn't a table. Hears pictures from ingame:

Code:
sender computer:

local info = {
['EnergyStored'] = format_thousand(energy),
['EnergyCapacity'] = format_thousand(maxene),
['FluidName'] = fluidName,
['FluidAmount'] = fluidAmount,
['FluidCapacity'] = fluidCapacity
}
local msg = textutils.serialize(info)

rednet.send(15, info)

main computer:

senderId, message = rednet.receive()
data = textutils.unserialize("message")

and

mon.write(data.EnergyStored.." RF")

You're un serialising the string "info". You need to unserialise the variable message.

I think Rednet can send tables directly, though.

Oh, you right, but i forgot to change it because I was testing something else, but it was "message"

With the correction you made, you're now trying to unserialize the string "message", not the variable message - remove the quotes.

shouldnt this part:

local info = {
['EnergyStored'] = format_thousand(energy),
['EnergyCapacity'] = format_thousand(maxene),
['FluidName'] = fluidName,
['FluidAmount'] = fluidAmount,
['FluidCapacity'] = fluidCapacity
}
local msg = textutils.serialize(info)
rednet.send(15, info)

be this?:

local info = {
['EnergyStored'] = format_thousand(energy),
['EnergyCapacity'] = format_thousand(maxene),
['FluidName'] = fluidName,
['FluidAmount'] = fluidAmount,
['FluidCapacity'] = fluidCapacity
}
local msg = textutils.serialize(info)
rednet.send(15, msg)

because now you are just sending over your table (with the rednet.send(15, info) and not the serialized msg

Good catch, Quessith - that's yet another problem.

Tim3Game, in addition to the the fix I suggested above, you'll want to change your rednet.send(15, info) to rednet.send(15, msg).

Depending on which version of CC you're using you can send the table without serializing/unserializing - but I'm not sure when that was added - 1.6 maybe? So, if you're using a recent version of CC you can simply use rednet.send(15, info) and skip serializing it into msg - just don't unserialize it into data on the receiving end - then get your info by using message.EnergyStored instead of data.EnergyStored.

Somewhere back in the early 1.5x range. Tim3Game's build can do it - otherwise the Lua prompt on the receiving computer wouldn't show the table contents.

Thanks you all for helping, its working, i edit the rednet.msg(15, info) to rednet.msg(15, msg) (Thanks Quessith) and removed the serialize and unserialize things (Thanks Dog) and now its doing what i wanted! http://tim3game.eu/upload/program3.png
