ListBox selected item

[logi2000]

i need to know if any item from a list box has been selected. how can i do that.

the problem is that when i use this code:
wwid = document.CustomerSearch.elements.lstResults.value;

if the user has not selected any item from the listbox, it is giving me an error.

 

[adam0101]

s=document.CustomerSearch.elements.lstResults;
wwid = s[s.selectedIndex].value;

Or if you just want to know if they selected something or not...

if(s.selectedIndex>-1){
alert('Something is selected!')
}
