Virtual Pet problems

Hello, everyone. I’m new to these forums and right now I’m having some trouble with my virtual pet game. The following problems I’ve been having so far are:

  1. I’ve been trying to decrease each stat (Happiness, Health, Hunger, Education) by one point every five seconds but when you run the swf file… well… you’ll see.

  2. I’ve been trying to make the icons (located at bottom right of the swf screen) appear at random times. I need some help with that.

  3. Rock, paper, scissors game: I’ll try to work on that. If you guys got any coding ideas, tell me.

Suggestions and help are highly appreciated. Thank you.
