The borders have no colouring at all but the gridlines _are_ present everywhere else except in A2:B123. they were just 'whited' out by colouring the borders white. When I first opened the sheet this morning and saw the small area of missing gridlines I thought, no problem. The data even though I fixed the alignment to center for the 2nd column. And the gridlines are missing in the 2 main 'fields' which makes it hard to differentiate All the gridlines are visible except for a small area.
Stands to reason that would be the first thing to ask. Unfortunately, wish I could but I can't post the file even with confidential info removed.
