How to pass multi-value parameters to DDS (data driven subscription)?

Using RS2005, how should multivalue parameters be stored in a database field so that a data driven subscription can properly read and use them?  I have so far had no luck using syntax of:

1)  parm1, parm2

2)  parm1,parm2

Do single qutoes need to explicitly wrap the values?  Can you please provide an example and a SQL INSERT statement using parm1 and parm2 to demonstrate what to store in the database field? 

Thanks!!
