If then statement based on selected value in table

I have a field in an add page where I select from a drop down list as\populatesd by a lookup table.
These are codes for billing, I am tasked with displaying a price range based on the code selected. Example if you select code LC1993 then we want it to display a message not to exceed $50 per unit claimed.
I have like 50 codes and each equal different dollar amounts. SO how in ASP pro would I do an if then or case statement for each code selected.
Thank you for any help
