————————-
command computer code:

rednet.open("top")
i,x = rednet.receive()
i,y = rednet.receive()

commands.x(y)
————————
but it did't work pls help :(/>

problem= commands.x(y)===>/x @p 1 2 3

how i fix it ?

sorry for bad eng :/

It should be

commands[x](y)

because commands.x looks for the command "x".

Another possibility is

commands.exec(x .. " " .. y)

And you coould also send the entire command at once this way.
