        alert(target);// checking that we are getting the right value.
        var openaddress=target.replace(/click/gi, "section");//create the new id for the section we want to open.
        alert('"#'+openaddress+'"');//Confirm that the correct ID has been created
        $('"#'+openaddress+'"').css( "color", "green" );//get the id of the click element and set …
