this error always comes up when i try to compile my scenario..

how do i fix it and why is it coming up?

umm you didnt finish the command, you gotta put:

tool structure levels\testing testing

You are getting that tool verb error becuase you didnt add the last testing bit too it.

i got it to work.
there should'nt have been a slash between testing and testing.
