print expression

Hi,

Here is my requirement.

I have  a sub report  which has data filled in through the database.The data will be like

CASH                 $100.00

CHECK             $100.00

VISA                   $100.00

MASTER CARD      $100.00

Now based on the value like cash,check,visa and master card i want to print the policy of  each.

Say if i get  cash as parameter then i need to print cash rules on the report.And if check then print check policy rules,visa then visa policy rules and the same  for master card.

I think you got my point of printing based on each tender type/payment type.if the payment is done by both cash and visa then print both policies/rules on the report.

Thanx
