:( From your post I got the impression that the repeats were fine. Unless you're not actually getting all 3 when you make three together or something like that, without my actually doing it it's hard to tell if there's something wrong with the pattern.
Here's a thought. When I do a lace pattern that calls for a yo after several knitting stitches, I find that that particular yo wraps around the needle in such a way that it brings the back of the stitch up. When I do it on the next row, I have to kind of roll it back down to get at the actual yo and not some other part of the stitch.
Also, Kelly pointed out somewhere earlier that most mistakes in lace comes from not realizing that there is a yo to purl on the back and just either slipping it off or assuming it's part of the stitch before it.
Or there's getting another pattern that won't give you so much grief!
