Brightspot, you may be experiencing what I did. I actually knit in the combined method which wraps the yarn in the opposite direction from standard knitting. If this is the case, than you will have to work your decreases in teh opposite manner than that described in most directions.
I'm not totally sure that's why you are doing, though, so carefully review the continental and combined methods on this page:
If you find you are working combined, let me know and I'll walk you through working the decrease. If you are truly working a normal continental then Peg is absolutely correct about the decreases. You can see more about them on Amy's page of decrease techniques.
