Sub Report Parameter Selections Via Values From Master Report Data

I am designing a report which will be used under the subreport control of a master report, now i am using a stored procedure for the subreport which has two parameters.

In the subreports dataset parameters tab, how can i mention the master reports columns, since i do not see the master reports columns here. since it is a different report.

If i use a hardcoded select query then i can just say

select address, city, state, zipcode from customer where (customerid = @customerID)

but i am using a stored proc. how to define the parameters under datasets parameter tab.

Thank you very much for the information.
