Dynamic text size changer

basically im wanting to find out how to enlarge the fontsize of the contents of a dynamic text box when a button is clicked.

button instance name is ‘button’ dynamic text name is ‘text’;

ie.

on ‘button’ would be somthing like this:

on (release) {
_root.text.setFontSize = 14; (or somthing like that…?)
}

Anyone know how to do this?

cheers.
