Hi. Without seeing the whole pattern it is hard to know exactly what to do, but, it sounds like the pattern has a repeating chain 4 in it. So, I am assuming that what it is telling you is to skip the two dc that were before the chain 4 (that was on the previous row since you are working back across the previous row) then skip the first three stitches of the chain 4 and do whatever stitch is next in the fourth stitch of the chain 4. Hope this helps.
