Lua Help

[Spirit]

Hello, I'm new to this forum, so sorry if this is the wrong section, or something along the line.
I have a Lua script(http://home.comcast.net/~nickpaoletti/lj2.lua) thats nearing completion, but has a couple bugs that need a little fix-up.
The first bug is that when the player chooses "scissors" the enemy may not choose something, but still get hit and lose health. His graphic does not show either when he is hit. (Video HERE
My second bug is that when the player is not standing, it seems he can still make a choice. (I'll upload a video soon if anyone would like to see.)

Anyway, thanks for any help :)... oh and take the IMG folder from this archive if you want to test the game. The script is outdated, so that dosen't matter.

This could be further simplified, but...
