Thanks Matt for your response. I updated Jquery to latest version but i did not help me so i rolled back SPServices to lower version which is 0.7.0.min.js and it worked like a charm. Thank you very much. Do you know by any chance why SPServices latest version did not support with latest version of Jquery or version 1.4.2.min.js?
Once again, thank you so much.
Thanks
