${PurchaseOrders.PL} is a picklist containing:

• optionA
• optionB
  
• optionC
  

I am trying to figure out how to create a Formula Expression that does the following:

If ${PurchaseOrders.PL} is optionA, ${PurchaseOrders.currencyfield}*.01
If ${PurchaseOrders.PL} is optionB, ${PurchaseOrders.currencyfield}*.02
If ${PurchaseOrders.PL} is optionC, ${PurchaseOrders.currencyfield}*.03

Thank you, I am new to the world of formula expressions and the skill in general.
