Javascript custom validator problem on DropDownList

[Assimalyst]

Hi,

I'm pretty new to javascript and i'm struggling to get a custom
validator working.

I have a dropdownlist populated by a datareader, the top value of which
is always "Please Select..." at index 0.

How can i code a validator to be invalid if "Please Select..." is
selected, but valid for any other value?

Here is my attempt:

function validateSurgeon NameDDL(oSrc, args)
{
args.IsValid = ([surgeonNameDDL. SelectedIndex].Value != "0");
}

However, this comes back invalid, for all selection.

Thanks.

function somethingSelect ed(dropdownlist ){
return dropdownlist.se lectedIndex>0;
}

function validateForm(fo rm){
var msg="";
if(!somethingSe lected(form.SEL ECTNAMEHERE)) {
msg+="Please select a surgeon\n";
}

....
if(msg){alert(m sg);return false;}
return true;
}
