How to send parameters for dymanic values in URL

Hi,

I have recorded A Script in Load runner 12.02 using web  HTTP/HTML protocol.

To parse different courses i used web_reg_save_param( )  function,

found below  results:

vuser_init.c(435): Notify: Saving Parameter "Courseid_1 = 11".
vuser_init.c(435): Notify: Saving Parameter "Courseid_2 = 10".
vuser_init.c(435): Notify: Saving Parameter "Courseid_3 = 9".
vuser_init.c(435): Notify: Saving Parameter "Courseid_4 = 8".
vuser_init.c(435): Notify: Saving Parameter "Courseid_5 = 7".
vuser_init.c(435): Notify: Saving Parameter "Courseid_6 = 6".
and so on ...

Now sending request containing corseid as parameter in URL.

I gets an error on replay , application doesn't recognize parameter [courseid]

Error -26627: HTTP Status-Code=404 (Not Found) for "http://localhost/course/view.php?id=[Courseid]" [MsgId: MERR-26627]

Can anyone help me in this?
