Are there arrows at the bottom of the chart or lines through the chart that indicate a section that you should repeat?
It's possible, too, that you can just continue the pattern until you run out of stitches.
A link to the pattern is your best bet to get specific help; or even a picture of the stocking.
"Trust the pattern!"
Time flies like an arrow, but fruit flies like a banana.
