Cast on new underarm stiches

Me again! I’ve come a long way, learning in the round. Now I have to cast on 5 stitches for the underarm. I’ve put aside on another needle the sleeve. I’m currently in a rib area, ie k1 p1. Can someone give me a link to a video as this was the most helpful tool on my last question. Thank you for helping.

That’s good news and so satisfying to make progress with new techniques.
What is the name of your pattern?
Is it casting on mid-row that’s the question? or something else?
Here’s a video for casting on in the middle of a row (see ~2:00min)

Thank you so much. With your response when I woke this morning it allowed me to continue knitting…most of the day today!!.
The pattern I’m knitting is Sandnes Garn: Kelly Sweater (#kellygenser). It’s meant to be easy but to be honest I think the translation from Norwegian to English is the issue as I’m able to decifer code but some of the instructions contradict each other. Here’s hoping I’ve done things right

You’re doing very well working your way through this sweater so far. Yes, these translations can be difficult but come back and ask anytime. Great looking lines to the design.
