if(document.frmEntry.optMethod != "undefined")
                    {
                        if (document.frmEntry.optMethod.selectedIndex == 0) {
                            strPrompt=strPrompt+'Please specify the Valuation Method\n';
                            if ( objFocus == null ) {
                                objFocus = document.frmEntry.optMethod;
                            }
                        }
                    }

$('footer, header').slideUp('slow').slideDown('slow'); // Grouped
$('#Sidebar img').fadeTo(5000, 0.1); // Combined

Please, I am using two javascript files, which has its own assigned worked, on a php page, however the jquery script stops working while the JSON2 script works.
This is how I implement both on the php page

    <script type="text/javascript" src="jquery.min.js" ></script>
    <script type="text/javascript" src="JSON2.js" ></script>

The link to the jquery file http://code.jquery.com/jquery-1.11.1.min.js

The link to JSON2.js :

function load_orderDetails() {
  // when this runs, disable the onclick in the function above.
