[jQuery] TexoTela select box manipulation modification

[codecowboy]

Hi Guys,

I am trying to add a function to the TexoTela select box manipulation
plug-in (http://www.texotela.co.uk/code/jquery/select/).  I am trying
to add a function called moveOptions() that will function like a cut &
paste from one text box to another.  There is already a function
called copyOptions() that copies a selected value from one select box
to another.  I copied the code from copyOptions() to my new function
moveOptions() to modify.  I figure that the only change would be to
remove the selected option from the 1st select box  after adding it to
the 2nd select box.  The concept is simple but my code is yielded
strange results.  The functionality breaks down when you try to copy
multiple options at once.  I am relatively new to jquery so I'm hoping
that it is something obvious.  Any help would be greatly appreciated.
Thank you in advance.

You can test out the code here:

Here is my function, I commented out all the different things that I
have done in an attempt to make it work:

/**
 * Move options to another select (functions like cut and paste)
 *
 * @name     moveOptions
 * @author   Sam Collett (http://www.texotela.co.uk)
 * @type     jQuery
 * @param    String to  Element to move to
 * @param    String which  (optional) Specifies which options should
be copied - 'all' or 'selected'. Default is 'selected'
 * @example  $("#myselect").moveOptions("#myselect2"); // copy
selected options from 'myselect' to 'myselect2'
 * @example  $("#myselect").moveOptions("#myselect2","selected"); //
same as above
 * @example  $("#myselect").moveOptions("#myselect2","all"); // copy
all options from 'myselect' to 'myselect2'

$.fn.moveOptions = function(to, which)
{
        var w = which || "selected";
        if($(to).size() == 0) return this;
        this.each(
                function()
                {
                        if(this.nodeName.toLowerCase() != "select") return this;
                        // get options
                        var o = this.options;
                        // get number of options
                        var oL = o.length;
                        for(var i = 0; i<oL; i++)
                        {
                alert(o[i].value + " -- " + o[i].text + " -- " +
o[i].selected);
                                if(w == "all" ||        (w == "selected" && 
o[i].selected))
                                {
                    //alert("1" + o[i].text + o[i].value);
                    //alert(o.toString());
                                        $(to).addOption(o[i].value, o[i].text);
                    $(this).removeOption(o[i].value);
                    //$(this).remove(o[i].value);
                    //this.remove(o[i].value);
                    //alert("2" + o[i].text + o[i].value);
                                }
                //$(this).removeOption(o[i].value, true);
                        }
                }
        );
        return this;
