I'm still trying to figure out how to read replies, send "thanks" and then delete the original question.
Please link to the pattern if you can. That'll help us help you.
I'm guessing you mean you repeat a specific number of rows? In that case you would finish row 1 and bind off. However, post the pattern link if possible so we can see it.
I will assume that you are knitting something that has many rows. I have encountered that type of wording before. It means when the pattern has reached the correct length make the last row done a Row1 pattern row and then bind off the stitches.
Sometimes a pattern will tell you to end with a wrong side row. That means that you complete a wrong side row before moving on to the next instruction in your pattern. In the next step, the right side is facing you.
"Ending with xx row" in a pattern means you've just finished knitting it. So do row 1 then BO.
