ComboBox ChangeHandler

Can anybody help me here.

I am trying to get a combobox filled with locations on my university, to call functions(? if thats the correct term for flash) that will display text, associated pictures, and call a flash animation....
Does anyone know how to do this??

just make a function on the parent timeline of the combobox, eg
function handler() {
//do some stuff...
}
then click on the combo box and type the name of the function in the change handler box, with no brackets....or you can apply it dynamically with

my_combo.setChangeHandler(handler);
