Need help with a pattern

Hello to my new knitting friends. I’m in need of some help on this pattern I’m stuck on I’m making a 6yr old hooded cardigan I’m up to the 31 St’s part of the pattern and really can’t get my head round the next part big thank you for anyones help xx

This is what I’m making

After you cast off 4sts at the beginning of the next 4 rows the pattern seems to be summarizing the sts remaining: 5sts for each shoulder and 21 sts in the center neck. If the next directions don’t tell you what to do with those sts, go to the Finishing or possibly the directions for the hood or the neckband. Those instructions may be of help with the sts
