Does it say “P2 tog” by any chance? I don’t know what you’re making but if the object gets smaller at some point, it could be P2 together rather than just P2. About the only time that I see “P2” it’s part of the “P2 tog”.
Sorry that I can’t be more help. Maybe check on-line to see if there are any corrections to your pattern. Ingrid “the Great” taught me that little lesson - if they misprint a pattern, the corrections will show up on-line. Just search for “corrections to ________” either the author or pattern.
It doesn’t say p2tog, that is why i am confused. It is a baby’s jumper and i am decreasing stitches for the arm holes. On previous lines it tells me to k2tog or slip stitches over but on this line it just says p2.
Some patterns write out the edge/border separately so that could be it. A lot of times when decreasing you don’t decrease every row…you alternate rows. I would just keep going and see how it looks.
