Your screen capture is a little too big to fit in a thread. This makes it very hard to read.
You say you want to delete rows which contains a "n", but only for a particular number of columns. Since you didn't specify the range try this example:
For Each cell In Range("A1:F20")
If cell.Value = "n" Then Range(Cells(cell.Row, "A"), Cells(cell.Row, "F")).Delete
When a "n" is found in the range A1:F20 then the columns A:F of that particular row will be deleted.
