How many stitches are cast on and which size are you making?
Which 2 rows are you asking about? I can only read row 2 easily.
The repeat with the (p3tog, 3 from 1) requires 4 sts and will leave you with 4sts. Is that what you’re getting?
Try using markers to mark off the various sections, (e.g. the k1p1 repeat, the p3tog, 3 from 1 repeat) before you work the row.
