Text animation

Hi all,
I am new to the Flash world and am pushing throught the learning process. I have come across a problem though I don’t know how to fix. At http://www.kayaconstruction.com/ I saw the text on the left side animates in a simple fashion. Well I’m trying to build on that and my attempt at http://chemgoof.t35.com/test.swf is not working as well. If you come in from the right over the text, it does what I want. But if you move the mouse over it really quick, the button sticks to the right side and doesn’t go back to its starting point. Is there an easy way to fix this? The only code I wrote for it is

animtext.onRollOver = function() {


animtext.onRollOut = function () {

where “_over” is just the animation moving right, left, right, left and then “_out” is just moving back to the left. I have stop statements at the start of each section too. Very quick and easy animation. Any help would be appreciated
