How to add parameters to a SQL Script job in OEM

Hi,

I am working on creating a SQL script job, from the parameters tab for the 'SQL Script' added my SQL code ( which have couple of variables). Now for the 'Parameters', what should I add?

Let's say my SQL code variables accepts 2 integers, can I add 30,60 (comma separated) for 'Parameters'? Is this the right way to do it? or else we cannot create a SQL Script job using Parameters?

Please suggest

Thanks in advance
