formular multiple select trouble

Hi all If i use multiple select fields in a from i use name[] to access it in php afterwards <select name=aname[] multiple> <option>test1</option> <option>test2</option> </select> i can then access in php $name and it has its the elements that were selected. my problem now is that i can't access name[] with javascript... if i try <javascript> alert(document.fo.neme[].value); </javascript> gives an error... is there another way to neme the seletc field? if i use name=aname then i only get one selected value in php..... thanks sebastian
