I have a knitting question related to a pattern

Hello...I'm knitting the following pattern: HOODED COWL:
Cast on 100 stitches on circular needle size 3 mm / US 2.5 with Merino Extra Fine or Karisma. Work in GARTER STITCH - read explanation above, back and forth. REMEMBER THE GAUGE! When piece measures 24 cm, cast on stitches at the end of every row in each side as follows: Cast on 1 stitch 2 times and 2 stitches 5 times (= 12 stitches increased in each side) = 124 stitches. At the end of next row cast on 28 stitches at the end of row = 152 stitches.

Knit until mid back on helmet hat by knitting 62 stitches from after the 28 stitches cast on mid front. Now divide the piece mid back to work back and forth from mid back (this is done so that the seam is mid back). Work in garter stitch back and forth until piece measures 10 cm / 4'' from the 28 stitches cast on mid front. Now insert 8 marker threads in the piece as follows: Begin mid back and insert first marker thread after 10 stitches, then insert the next 7 marker threads after 19 stitches, there are now 9 stitches on needle after last marker thread. Continue in garter stitch. On next row from right side, increase 1 stitch on each side of every marker thread - read INCREASE TIP. Increase like this approx. every 3 cm / 1'' 6- 7-8 times in total = 248-264-280 stitches. Work until piece measures 58-60-62 cm / 22 3⁄4"-23 5/8"-24 3/8" in total. Bind off with 2 strands. Pick up from right side 158 stitches around face opening on a short circular needle size 2.5 mm / US 1.5. Purl 1 round, knit 1 round, purl 1 round, knit 1 round. Then work rib (= knit 1/purl 1) for 6 cm / 2 3/8''. Bind off stitches with knit over knit and purl over purl. Fold edge double towards wrong side and fasten it.

I am stuck at this point and do not know how to move forward:

Knit until mid back on helmet hat by knitting 62 stitches from after the 28 stitches cast on mid front. Now divide the piece mid back to work back and forth from mid back (this is done so that the seam is mid back). Work in garter stitch back and forth until piece measures 10 cm / 4'' from the 28 stitches cast on mid front.

What do I do? Can someone help me?
