Help

I'm kind of stuck, stalled, confused. I'm doing the top up version and I've never worked the heel like this before. On the gusset where you do the short rows and it says to w & t, what I'm doing is slip stitch, wrap and turn. Is this correct? I don't think I'm doing this right and I'm stuck. I'm not coming up with the 98 stitches when done. Any help would be appreciated.
