HI,  
I am new to flash game programming and I am on a project for the game Ice Age which i found in a ebook(i dont have CD just Ebook) Game Design Demystified by Job Makar. The data given in that book was not sufficient. I have developed all the graphics & movie clips required. Now I am having problems in the following areas:

1. He has told to use level data in XML format which i don’t know how to incorporate in flash.
2. I am unable to understand level editor. However i will be satisfied even if I make 1 level.  
3.Few of the functions used in action script are not defined viz addFrictionAndGravity(), createTempPosition(),detectFlag(),checkFloor(),renderScreen().  
4.When i test movie nothing comes(no errors & blank screen).

It will be a great help if anyone could help and give me strategy where to start and what steps to follow. This is my school project and I wanna finish it fast. PLEASE HELP…

The ActionScript in use is as follows

game = {};  
game.bg = {};  
game.bg.clip = gameClip.bg;
