ICBM mod launcher as Peripheral

Hey There
First of all sorry for my bad English but Im Austrian.

When I run the following test code I get the Error Message: attempt to index ? (a nil value) an I don´t know why.

local IcbmSide = "right"
icbm = peripheral.wrap(IcbmSide)
icbm.launch()

I assume the error has a '3' in there somewhere too. That's the line number.

You would get that error if there isn't actually a peripheral on the right.

Yes the error has a "3" in it.

ICBM's peripheral I believe is the terminal you normally launch missiles from. This is of course on the older version I don't think the newer version even had peripheral support since it switched authors. Which of the three parts are you trying to wrap with the computer?
