If you want to capture dynamic values which is returned by 
server then in that case you need to do manual correlation,
and for doing manual correlation you need to find out the 
boundaries(left as well as right) under which that dynamic 
value is returned by server and then add a new 
web_reg_save_param("Lb","rb","ORD",LAST) function along 
with correct left and 
right boundaries to capture that value n a right ORD
and v need to add another functions like lr_output_message
("The value of the session:%s",lr_eval_string
("parametername");using this function we 
capture the dynamic value in load runner.The result we can 
see in the execution log in vu generator. Each time we need 
to copy the dynamic value in the text file.
