</div>

I am using the following code. Where \*\*list \*\*is an instance of a **ListBox.**

```auto

function displayDetails(c)
{
   trace("I am in displaydetails");
}
list.setChangeHandler("displayDetails");

```

The call to displayDetails function is NEVER done.  
Why?  
Any ideas, hints?  
PLEASE help.:hangover:  
Leo.

Are you sure that `setChangeHandler` is a function of a list component?  
What effect are you trying to create exactly?

Hi there…  
Thanks for the reply.  
The effect is that, for every change on the List Box, a certain function wil be called.  
I tried to upload the file, but is too big, can i send it to u?  
Thanks.  
Cheers.  
Leo.
