Rails spinoffs - Feb 2006 - Not able to see length in another function

Hello everyone,

I have the following code that builds <option> into a <select>. 
buildModel() is called first, then setModel().

For some reason, I can''t get the length of the "model"
options in
setModel(), but can after they are built in buildModel();

function buildModel(originalRequest, json) {
    var model = $(''model'');

    //might need to clear options
    //model.options.length = 0;

    $H(json).each(function(node){
            model.options[model.options.length] = new Option(node[0], node[1]);
    });
    alert(model.options.length); // alerts the proper length
}

function setModel(smodel) {
    var model = $(''model'');

    alert("inside setModel length is: " + model.options.length);
//length is zero

    for (var i=0, len=model.options.length; i<len; ++i) {
            if (model.options[i].value == smodel) {
                model.selectedIndex = i;
            }
    }
}

Any ideas what could be causing this?

Thanks for any help,
Kevin

There are two pieces of information missing.

1) How is model defined (the HTML / DOM bit).

2) How is setModel being called?

Also of interest ... what browser is causing you problems?  Do you
have a site we can look at?
