I'm new to coding and I felt like playing around with wireless modems and I think I messed up, I'm wondering what I'm doing wrong it says on line 4 there's a "then" expected but it's already there,
rednet.open("right")
id, message = rednet.recieve()
while true do
if message = 1 then
rs.setOutput("down", true)
elseif message = 2 then
rs.setOutput("down", false)
end
end

Should be:
rednet.open("right")
id, message = rednet.recieve()
while true do
if message == 1 then
rs.setOutput("bottom", true)
elseif message == 2 then
rs.setOutput("bottom", false)
end
end
Same mistake: if you want to check if something matches something, use ==

This is covered under the

Also, I'm not sure if "down" is a valid side. Use "bottom".

Tried bottom. Didn't seem to work either so I moved the computer and put redstone in the back and using "back" didn't work either.

Oh so there's another bug. Yeah, I see. receive will never be a number, since you can't send numbers over rednet, only strings.

Still doesn't work. I changed 1 into "on" and 2 into "off" both with and without quotation marks. What am I doing wrong?

elseif message == 2 then

Thank you, I feel stupid for making so many mistakes in so little amounts of code,

You can send numbers over rednet. Tables, too.

It seems that the OP put Ignore this :P/>
id, message = rednet.recieve()
It should be
id, message = rednet.receive()
To print the valid sides do this
for _, side in ipairs( rs.getSides() ) do
print( side )
end

… depending on the version of ComputerCraft installed.

True, though for unqualified statements of what one can or cannot do, the current version is the one to base things off of. :P/>
