Cant figure this out for the life of me!

Hey Jeff,
WB is proving to be something of a PITA for me. The Nikkor 85mm really seems to take fantastic pics. Everytime I try to custom set the WB with a white piece of plastic in the tank it doesnt work? I think I am following the instructions right. I can get it to work in other situations. Just have to keep messing with it I guess.
Oh ya, RAW is not likely for a beginner like me. Mabye someday but probably not!
Thanks
