Crochet pattern ad - Did you catch the boo-boo in the ad?

Here's another short post of something funny that I found while "surfing". Annie's Attic is having a clearance sale, with pages of crochet-related stuff on sale. That's worth searching through!

So I found a crocheted top that I like, (note-remove that silly drawstring!) and spent some time thinking about the yarn, color, size, cost, etc. The pattern is right there (add to cart), they recommend 2 different yarns and look you can order the yarn right there (add to cart), but with the yarn information, there's something funny going on! For each yarn they have a choice of size and how many balls of yarn you will need (to make it super easy to add to cart). Then each yarn gives information about what size knitting needle to use, and the knit gauge. Hello, AA!! That's a crochet pattern! What size crochet hook do we need to buy? (why can't we add to cart?) What's the crochet gauge? Who put together this ad? Who did the copy proof on this ad? Where's the crochet employee who should have caught this blunder?
