            var extension1 =      fileUpload1.substring(fileUpload1.lastIndexOf('.'));

            var ValidFileType = ".doc , .pdf , .xls , .xlsx, .docx, .jpeg, .jpg, .png";

            var id = document.getElementById("fup").value;

            if (id.length > 0) {

                var extension = id.substring(id.lastIndexOf('.'));

                var fsize = $("#fup")[0].files[0].size;

                if (ValidFileType.toLowerCase().indexOf(extension) < 0) {

                    alert("Only doc,pdf,jpeg and xls files allowed.");

                    return false;

                }

                else if (parseInt(fsize) > parseInt(1024 * 1024 * 3)) {

                    alert('File size must 3 MB or below.');
