Hi all,

I’m trying to call an function in flash from xml. so I used \<a\> tag and asfunction. But how come when it calls a built-in function in flash, it works. and when it calls a custom function, it just won’t work???

function customFunc(a){  
trace(“here”)  
}

these are in my xml file:  
\<a href=“asfunction:trace,here”\>Click\</a\>  
– okay this one works  
\<a href=“asfunction:customFunc,whatever”\>Click\</a\>  
– this one doesn’t

Thanks in advance:)
