I am lost with this pattern

I am a fairly new knitter and trying to do a baby sweater. It is am Emu pattern with Raglan sleeves. when i got to the dividing up i was fine until i was at the end of the left front. repeat these 2 rows until 30 stitches remain ending at front edge .Shape neck. cast off 10 sts p to end…but it is knit row so do i do this and cast off the border at front?

Welcome to KH!
What is the name or number of the sweater?
If you end at the front edge of the left front, the next row is a purl row (assuming this is basically stockinette). Remember that the left front is left as you would wear the sweater.
