I notice that you did not use 'my' for all instances of $counter. I thought that was part of the requirements for using 'my'. At least I think that's the way I've seen it used. (I think - now I'm not sure of anything)
One other thing I see now is that the comments '#odd rows' and '#even rows' should have said columns, not rows.
