    use the same cfloop inside your js code (assuming it is IN THE SAME
    PAGE, not in a separate file).
    obviously, your #count# variable must be set BEFORE the js code...

    something like [not complete function]:

    function validatefields(){
    var errstr = "";
    <cfloop...>
    (document.forms[0].elements["item_val_#i#"].value=="") ? errstr =
    errstr + "\nField Myfield#i# must have a value!" : errstr = errstr;
    </cfloop>
    .....
    }

    but i would suggest you better validate input server-side...

    The easiest way is to use cfform and cfinput. Then you can use the required and message attributes for cfinput.
