multiplication in smartforms

Hi Guru's,

I am working on 4.7c. My requirement is i want do multiplication between two columns and result should be display in third column which is not included in structure in smartform. Presently i achieved this by adding that third column as field in table structure and i am doing multiplication in calling program itself. But i wanted to know can i achive this in smartform(can we do math calculation like devide,add,multiply etc. between fields on smartform)

Regards,
