ActionScript 2.0 :: Using A Flash Template With Xml File?

i am using a flash template with xml file.i have to made a link here

Code:
<image imageUrl="_pic1.png" link="asfunction:_root.more_click_func, termsofuse"/>
<image imageUrl="_pic2.png" link="#"/>
<image imageUrl="_pic3.png" link="#"/>

i would link to link this to an interne part of the flash wich is already linked in the flash menu, but i can't !the xml function is :

Code:
function more_click_func(number) {
tempNumber = number.split(" ");
number=tempNumber.join("");

[code]....

I tried something like :

Code:
function test_link(string) { _root.gotoAndPlay("s1"); }
and
<image imageUrl="_pic1.png" link="asfunction:_root.test_link"/>

but it didn't work !
