Without seeing the full instructions for the row, I'm guessing that you are supposed to Yfwd, (k1 p1)twice, k1 over and over? Which would be:
Yfwd, K1, P1, K1, P1, K1, and just keep repeating that. For example, if you were supposed to do that 10 times, and began with 50 sts, that would add on 10 sts and you would have 60. Does that make sense with the actual numbers you're supposed to get?
