Error while executing GIMP scripting

Hello,
I am very new to GIMP, I am still in a learning stage. I have been trying to take a step by step effort to do the same. I am trying to execute a script and I am getting the following error message.
GIMP Message
Circle Message
Error while executing
(script-fu-circle-path 3 7 10 33 21)
ERROR: too few arguments (see errobj)
OK
Since I am new to this, I was not sure of how to proceed further. I would be glad if someone helps me with this error pop up. I have a project to complete and any help on this is appreciated.
