Here is my script: http://jsfiddle.net/9cnGC/11/
<div id="callus">
<div class="def">111-1111</div>
<div class="num1">222-2222</div>
<div class="num2">333-3333</div>
<div class="num3">444-4444</div>
<div class="num4">555-5555</div>
<div class="numnames numname1">location 1</div>
<div class="numnames numname2">location 2</div>
<div class="numnames numname3">location 3</div>
<div class="numnames numname4">location 4</div>
</div>
$(function() {
    $(document).ready(function() {
        $('.numnames').hover(function() {
            $(".def").toggle();
        });
        $('.num1').hide();
        $('.numname1').hover(function() {
            $('.num1').toggle();
            return false;
        });
        $('.num2').hide();
        $('.numname2').hover(function() {
            $('.num2').toggle();
            return false;
        });
        $('.num3').hide();
        $('.numname3').hover(function() {
            $('.num3').toggle();
            return false;
        });
        $('.num4').hide();
        $('.numname4').hover(function() {
            $('.num4').toggle();
            return false;
        });
    });
});
I was wondering if anyone can help me with this fiddle and maybe clean it up a bit so it can run more efficiently?
I believe it is because there is another instance of jQuery running on the page. Which is messing with this script here, but I am not sure what is wrong with it.
Here is the page that has the messed up display logic. http://ben.chmark.com/mdcp/index.php/prescriptions/transfer-prescription
There is a top right module (give us a call). There should only be one phone number shown at any given time. It is modelled after the jsfiddle I provided up above. It runs fine on all the other pages except this one. I'm stumped :(
Thanks in advance
