can anyone help me ? thank you !!!!!!

Hi,








When asking for support please always state what are you using and which version.





Assuming you are using the "db_search" example, and a recent JChem version ... at first glance it seems you a have set a layout in setup.jsp with wrong syntax.


Deleting / fixing that layout string should help.





Best regards,





Szilard

thank you very much, I have fixed it, using JchemBase 5.02 , db_exemple. Merci
