Hi, I have a movieclip that has a text field and a button layer. The button then has a movie clip that plays an animation on the hover state (roll over). When i run the SWF it's fine, the animation plays when I hover over the movieclip. BUT When I add the following code, the code works (trace data displays), but the movieclip no longer plays the animation when the mouse rolls over it. catagories.nav_fashion.onPress = function() { var category_id = "fashion"; trace(this + " has been pressed"); trace(category_id + " is now the selected category"); }; Code (markup): Does anyone know why the animation no longer plays?
