I have a little problem with my check all javascript here. When I click the master checkbox, all the dynamic generated checkbox will be selected and that's good. But, when I click the master checkbox once again to deselect it, those little checkbox didn't deselect except the first one.

The master checkbox code is below:
<input type="checkbox" onClick="SetChecked(1,'chkSample');" >

The Javascript is below:
function SetChecked(val,chkName) {
dml=document.forms[form];
len = dml.elements.length;
var i=0;
for( i=0 ; i<len ; i++) {
if (dml.elements.name==chkName) {
dml.elements.checked=val;
}
}
}

Thanks for the help.
