Help with working rows

Probably quite basic but could somebody please tell me what “work 14 rows in 55 ending on a purl stitch” means.
There are only 51 rows in the whole pattern.
Row 15 is just purl.

I’d be really happy for any help
Thank you x

Are you sure it’s 55 (fifty five) and not SS (stockinette stitch)? What’s your pattern and can you link to it?

Well that’s how to prove you’re super stupid. Yes, when I put my proper glasses on, in says SS!!!
I’ve been trying to work it out for the last couple of hours.

Thank you so, so much x

Most of my problems are because of misreading. I understand all too well. I’m glad you can go on now.
