Definitely, a picture or two would help. If you can take a close up so that we can see the rows in detail, that would be great.
No ending with row 4 means to complete row 4.
ETA: The key for the pattern is correct but may be a little confusing if you're used to reading charts.
Usually the key might tell you a dotted box is purl on the RS, knit on the WS and an open box in knit on the RS and purl on the WS.
The designer has simplified it by telling you that all the RS rows are knit. Then on the WS rows, the dotted box is knit and the open box is purl.
Try this to get started (if you haven't already): follow the written directions for rows 1 and 2 (Green)
Row 1: Knit all stitches.
Row 2: P14, K2, P15
