Looping background question, and how to stop a loop i dont want

again fixed, now all i need to know is how to pause the background, and then have it continue playing when the “aim” animation is finished.

heres the AS2.0 of the actions: // set counter
counter = 0;

fire_button.onRelease = function(){
counter ++;

also, ive uploaded the flash to rapidshare for anyone who wants to look at it to see if im going wrong in regards to the second character looping his second animation
