You put the marker on the needle between sts, not in a stitch. So k2, put the marker on, work the st repeat, put on another marker, k1, put another marker on repeat the sts, place the last marker and k2. On the following rows, just move it from one to the other so it travels up the piece as you knit; it's used to show you where the YOs go for the incs.
