I have a parameter that is used in my sql command and I want to be able to change the value of it if it reach a certian criteria. For example the user enters the string "FDT" i want to change the parameter to equal "7" before it gets sent to the database to gather the records. How can I accomplish this??

Any help would be awesome.
