i changed document.form.description.options[description.selectedindex].value document.form.description.options[description.selectedindex].text, still doesn't work. please advise. tia.

if plan use 

document.getelementbyid("description").value

in switch case, must add "value" attribute option tags like

<option value="scholarship">scholarship</option>

this code doesn't have in loop too, can do

function fundsource() {    var val = document.getelementbyid("description").value;         switch (val) {             case "select":                 document.form.scholarship.style.visibility='hidden';                 document.form.description_other.style.visibility='hidden';                 break;             case "wall of friends":                 location.href= url                 break;             case "scholarship":                 document.form.scholarship.style.visibility='visible';                 break;             case "other":                 document.form.description_other.style.visibility='visible';                 document.getelementbyid("descriptionspan").style.visibility="visible";                 break;         }  }

hope helps.
