            {
                var selecteditems = CIMtrek_Attachement_1.split("\\");

                var filename = selecteditems[(selecteditems.length-1)];

                alert("selecteditems=666==>> "+selecteditems);
                alert("filename=66666==>> "+filename);

                nodeField = createNodeField(xmlDoc, new Array("FieldName"), "Record")
                nodeField.attributes[0].value = NewFormFields[i]

                nodeField.appendChild(xmlDoc.createTextNode(filename));
