[FLASH8} help with scrolling thumbnails

programming flash
1

ok, i am applying what i learned in the adding thumbnails tutorial to my own site and my fla size is 800X600, and my hit_left movie clip is at x=175. i have 12 diffrent thumbnails that are loading but it shows it only a few after the hit_right movie clip. i want it to load starting at the left. what do i do!!
xml looks sort of like that but more
i commented out the parts of the code i didnt use because i had no need for them.
