I'm writing a form that uses JavaScript to pre-fill elements with cookie values. I have it mostly working, but I can't get the code to pre-choose select menu entries to work.

Here's my JS code:

Code JavaScript:
function cookieMake () {
 
    var formelms = new Array();
 
    formelms[0] = 'input';
    formelms[1] = 'textarea';
    formelms[2] = 'select';
 
    for (b=0; b < formelms.length; b++) {
 
        var tag = formelms[b];
        var elms = document.getElementsByTagName(tag);
        var count = elms.length;
 
        for (var i=1; i<count; i++) {
 
            var item = elms.item(i);
            var title = item.name;
            var type = item.type;
            var value = item.value;
 
            if (tag == 'input') {
 
                if (type == 'radio' || type == 'text') {
 
                    ints.setSubValue (title, value);
 
                }
 
            } else {
 
                ints.setSubValue (title, value);
 
            }
 
        }
 
    }
 
}
 
function cookieFill () {
 
    if (ints.cookieExists ('ints')) {
 
        var formelms = new Array();
 
        formelms[0] = 'input';
        formelms[1] = 'textarea';
        formelms[2] = 'select';
 
        for (b=0; b < formelms.length; b++) {
 
            var tag = formelms[b];
            var elms = document.getElementsByTagName(tag);
            var count = elms.length;
 
            for (var i=1; i<count; i++) {
 
                var item = elms.item(i);
                var title = item.name;
                var type = item.type;
 
                if (cookval = ints.getSubValue (title)) {
 
                    switch (type) {
 
                        case 'select-one':
                        var selectarr = document.forms['theform'].title;
                        var optscount = selectarr.options.length;
 
                        for (var a=1; a<optscount; a++) {
 
                            if (selectarr.options[a].value == cookval) {
 
                                selectarr.selectedIndex = a;
 
                            }
 
                        }
                        break;
 
                        case 'text':
                        item.value = cookval;
                        break;
 
                        case 'textarea':
                        item.value = cookval;
                        break;
 
                    }
 
                }
 
            }
 
        }
 
    }
 
}

Firefox's Firebug shoots me the error, "selectarr.options has no properties," for the line under case "select-one" in cookieFill:

Code JavaScript:
var optscount = selectarr.options.length;

If I use the full name of the element instead of a variable, the same kind of error occurs.

If I try to get the length for the select element itself, instead of the options object, the error doesn't appear; the result is just 0.

Can anyone help me out here?
