Hittest that ALWAYS don't work my way

Hiya guys, long time no see, eh?
Havn't been here for like 2 months, been doing my homework :zombie:

I got stuck on a hitTest in the last 20 minuits. So i thought you guys could help me work this out:
I got a movieClip called <guy> Instance. also I got 14 movieclips that are different but the same named <r1> <r2> .. <r14>
now I have scripts that make r1 or r2 play at random.
now i have a hitTest that makes <guy> smaller everytime it's hit. well by one of the "rocks"
It must can be done,
But then, I can't do it
THanks guys for ya help!

perhaps a sample should help
