first thing first.. make sure you choose the correct exchange code.
Mine was Exchange certificate 2.
put in the date that is on your card (for example) 12 01 05
change the drop down menu to the correct letter code (for example) WDW
type in the number that comes after the WDW: (for example) 034
Skip the TR #, if I'm not mistaken. (for example TR: 216) skip that number.
And enter your card number that follows the TR:216 and enter your card # (for example) 327
