Help with a pattern :)

Hi i’m having some issues with a pattern and im wondering if anyone would know how to approach it, image

I currently on the right half of the pattern and have 15 sts on my needle and the pattern says

‘cast on 15, patt.15 sts. left on needle (45 sts)’

I would only have 30 stitches on the needle so I dont quite understand where I would have 45? Im also a little confused on the pattern I am meant to continue with?

Welcome to KH!
What is the name of your pattern and the pattern number or company name?
It does seem to a problem of stitch count. Knowing what the project is and getting a look at it may help.
The pattern stitch that you’re meant to continue is the wraps and then later dropping the wraps.

Hi thank you for your reply! :)) heres a screenshot of it


Thanks for the photo. All I can think is that you cast on another 15sts. The pattern clearly requires 45 sts to proceed. The extra sts are likely to be at the face opening which needs to be wider than the back of neck opening.
It may take a bit of trial and error to get this right. I don’t see any corrections online but that often happens with vintage patterns. A lifeline at the current place may be helpful.
