Take a look at the yo video
under the Free Videos tab, Increases to make sure that you're doing the yo correctly. It occurs between
sts and doesn't use one of your sts. The same for the yrn which involves bringing the yarn to the front between the needles, then over the right needle and around to the front again for the purl sts.
The sts you gave add up to 182sts so it should all be ok.
