I'm fairly new to citrus.. and even to newer to grafting. I just started forcing my miewa Kumquat on root stock... My guess is you should starting forcing. Is your green house heated? I too followed MrTx page directions.. and like you I did more than one.. and the upper one was only one to work. that was the first one I did too..
here are pics of my citrus and grafting..

Awesome> Thanks Gina *BabyBlue*! How's George doing?

Cheers, Barrie.

George is doing pretty well.. he is bouncing back nicely. he is currently covered in flower buds and new branch buds. As soon as I can get a decent picture of him I'll be posting it.. most of the pictures I've taken of him you can't really see the new growth. When the buds grow out I'll snap some pics..
I am going to start grafting another tree tomorrow. give Nola a sibling.
Nola might be heading to Louisiana in a couple of weeks.
