onChange and Nothing Chosen

[scoobydoo987]

Is there a way to tell if the user hasn't clicked the dropdown box of choices? I know that you can call a function and do things with onChange but I need
+ ' ' + comSignature
to also be added to ['linerTextAndDescriptionAdj_" + vid + "'].value even if the user doesn't choose anything?

Does anyone know how I would do this?
--------------------------------

0NewTd13.innerHTML = "<select class=copy style='background-color: #FFFFFF' onchange=\"document.forms[0].elements['linerTextAndDescriptionAdj_" + vid + "'].value = linerText + ' ' + this.options[this.selectedIndex].innerHTML + ' ' + comSignature; document.forms[0].elements['DescriptionAdj_" + vid + "'].value = this.options[this.selectedIndex].innerHTML;\" name=descript_" + vid + "><option value=''>-- choose description --</option>" + descriptionAdjOptions + "</select>";
