Add Command Crystal Report not updating parameter

[liona]

I have a problem I have added a command to my crystal report that calls a stored procedure and should turn a number. I have also added a parameter to that procedure to make it dynamic. The problem I am experiencing is that when I bind this result to an unbound field the parameter doesn't change. It is static. And results in an error of having to Verify the Database to update the report. Is there another way I can do this. Is this a glitch with Crystal.... select test.pkg_s_e.get_cnt_ws('{?P_WS}') from dual
