Call a function in another class

[COLOR=#000000][FONT=verdana]Hi, I’m just beginning to learn AS3. Here’s what I intend to do. Create a base movie. Load a footer into the basemovie. When a button is clicked in the footer, I want to call a function in the base movie to load a page on the top.[/FONT][/COLOR]

[COLOR=#000000][FONT=verdana]Please refer to the attachment. Basemovie is the main class, that loads the footer swf. In footer.as, I want to be able to call basemovie.fLoadContent() from the function fClickNext(). [/FONT][/COLOR]

[COLOR=#000000][FONT=verdana]Can someone please guide? Will be really appreciated.[/FONT][/COLOR]
