XML FLASH question?

Hi, I’m relatively new to Flash so please bear with me.

I have set up a .XML to connect with Flash. My friend wrote part of it for me to use as a guideline…

In the FLASH, he has a link to click which calls in an actionscript through

<a href=“asfunction:_root.more_click_func,999999”>EXAMPLE SAMPLE</a>

I googled the asfunction and learned about it.

Where is the _root.more_click_func? I looked in the Main Timeline actionscript and no function is created there. I also looked into the movie clip actionscripts and nada.

Any help and insight would be appreciated.
