Hittest game help

Can someone help with this hittest problem. I have 2 MC on the main timeline, one is the main hero, the other(s) are randomly generated snowflakes. The hero is controlled via left, right and spacebar keys. When the snowflakes hit the hero I want the snowflake to dissappear and tally 1 point. I’ve been putting the hittest AS on the snowflakes. Should I be putting it on the hero? I can’t attach the file because it’s too large but I can email it. If anyone can take a look at and tell me what the heck I’m doing wrong it would be greatly appreciated.
Thanks in advance,
Brett
