... I think it might be nearly what it shold be, but in the

%if (i>2) ....

you forgot the &

%if &i>2 %then ....

might do what you want. I'm not sure, because I don't know what you want, I
only see what you did!

A good method to see if that is really that what you want:
decrease your counter from 2000 to 5 and activate the option MPRINT. That
will show you, what is generated and you'll see if that is really what you
wanted.
