Hiya

Got a form with 3 client-side dynamic dependent list boxes which is working wonderfully - except that some users see the initial value of the child boxes and dont use the drop down list to select - is there any way to add a 'please select' option to the initial value, bearing in mind that this is a dynamic dependent list?

Just do a javascript check using selectedIndex.

ie, upon form submission, call a function that checks each dropdown.

ie.

function checkme(){
if (document.all.selectBoxName.selectedIndex == 0) {
alert("please make a selection on dropbox1";
return false;
}
}

it's MSIE compat code, as that I personally don't support NN. selectedIndex starts at 0 which is the first entry in the drop down box.
