Thank you very much for your hel, Roger. The first part worked very well and now I manage to include the variable labels, thanks! however, I got some problems with the 2nd part . bmjcip S_1 S_2 S_3, cformat(%8.2f) option ftrim not allowed I still tried using other cformats and even xmlsub, but none of them worked. Can you please help me? thanks!
