Combobox component

I’m trying to mack a simple drop down list where each selection has its own value. I have a combo box with the following parameters.
Editable = false
Labels = choice1, choice2
Data = 0,1
Row Count = 8
Change Handler = blank

I have an instance name of “type” on the component. Now I have a dynamic text field with a var of “price” and on the first frame of my movie i have this code
if (_root.type == 0) {
_root.price = 10;
if (_root.type == 1) {
_root.price = 20;

But its not showing these values in my text field when i select those choices. Any suggestions?
