Combo box list NOT linking to URL?

1

Hi i am having difficulty with a combo box list. I want to use it in a kind of quiz. so i can give feedback on their answer by using dynamic text. However despite filling in all the potential answer choices ok, in all the books it only says how to make their choice link to a URL. But i just want it to make dynamic text aapper in the same keyframe. Can you help?

my_array = ["blue", "red", "yellow", "green"];
for (var i in my_array) {
	my_combobox.addItem(my_array*);
}
my_combobox.setChangeHandler("myHandler");
function myHandler(component) {
	myTextField.text = component.getSelectedItem().label;
}
