it is easier to help if you link your pattern. I googled it and think this is the one:
So, what you do is mark the center stitch to know where you do the yo.
Then before and after the center stitch, you make a yo on the right side rows. The rest you work in stochinette stitch (work knits on RS and purls on WS, but the button band: knit on both sides, forming garter stitch.)
if you know how to read your knitting (some do and some don't) you can see the center stitch. If not, I recommend marking it by putting a stitch marker in front of it (from the right side of your knitting). when getting to the marker, you make the yo, then slip the marker and then work the center stitch, then do another yo.
Be careful, that the marker does not "dive under" the yo and gets missplaced. That may happen easily and needs to be corrected then. (no problem, just check it when you get to the marker on the WS rows).
This pattern falls into rythm as soon as you have made a few rows and the strip of holes becomes visible.
