hey Mickey
Yeah i already tried putting outputs in the code block to see if it worked
but nothing was output
and i just checked that optomization thing u were talking about and its set
to none
i asked lecturer today what the problem was and he couldnt work it out
either so he just walked away after awhile!
thanks for the help
