Row 7 seems to be missing something. There's 2 k sts from the k2 p2 on the previous rows, yet you only kfb, p2, across the row? That uses 1 of the knit sts, not both. Or should it be kfb, kfb, p2? That would give you 4 knit sts and 2 purls. Does it say you're to end up with 80 sts or that's how many you did end up with? If you kfb twice then p2, I think you should end up with 90 sts which works fine with k4, p2.
