Char Falling Through Ground W/ Specific Code

Hello all, I searched the boards and have read a good amount on this topic which seems to come up quite often, so I apologize for yet another one. But im wondering if there is an efficient “fix” to my code rather than a full rewrite. I’m not the greatest coder (i prefer design) but with the help of a couple people and various guides Ive managed to learn a lot quickly.

Im having trouble troubleshooting a platformer game issue thats happening. A friend wrote most of the code for a previous game we did, and hes no longer available, which is fine with me since I want to become more proficient myself. Just kinda stuck at the moment.

I’ll will upload/attach the FLA since its small and stripped down to the bare bones. You’ll see the problem right away when you load up the swf.

I would love to find the best way to alter to the code in order to give me near-flawless hitTesting between the character and the ground.

Very beginner issue I think, thanks in advance for any tips!
