I've just looked at the pattern...and it seems they've got a few words in the wrong place...not very helpful for a newbie.
Hope someone else will check me out...but here's my take:
That line (where you're starting to make the sides) oughta read:
(I'm just using the first number for simplicity.)
Next row: Cast on 9 sts (1st side). Turn. Knit these sts. P1 (This is the way the sides are divided from the bottom & creates a "turn".) Knit across the bottom (6 sts) to the last st. P1. Cast on 9 sts (2nd side). 26 sts. Turn
Next row: Knit
Next row: (RS). K9, P1, K6, P1, K9.
Does that make more sense?
Rep last 2 rows until work
