i have this script for setting a delay ...now, the first time i run the movie the delay works, now, if i call the script a 2nd time, the delay doesen't work anymore ...please look over my script and tell me if there's something wrong ...

code:



stop();



first = function () {

	    xPos = _root.mcMenu._xmouse;

	    yPos = _root.mcMenu._ymouse;

		

	           if (xPos<-475 or xPos>475 or yPos<-110 or yPos>48) {

				   

				   

		                 _global.delay = 1;

					     myInterval = setInterval(delays, 2000); 

		                 delays = function () { 

						 

		                  

		                   

		                   if (delay == 1) {

							   clearInterval(myInterval1);

			                   _root.mcMenu.onEnterFrame = function() {

				                     _root.mcMenu.prevFrame();

				                         if (_root.mcMenu._currentframe == 2) {

					                          delete _root.mcMenu.onEnterFrame;

				                          }

			                   };

					       }

						   

		                     clearInterval(myInterval); 

			              };

		        

	                } else {

						

		             _global.delay = 0;

		        }

};

myInterval1 = setInterval(first, 10);
