Welcome to KnittingHelp!
On the directions for row 4 you work the 4th row of the cable pattern so on row 5 you would work the 5th row of the panel, on row 6 the 6th row of the panel and so on. On row 29, work row 1 of the panel and continue to keep track of the cable panel rows.
Would you please edit the pattern instructions so we don’t have the cable panel? Just knowing it’s a 28row repeat is enough and it will help us avoid copyright problems.
