Can anyone steer me on the right track, I have a spreadsheet with
loads of columns which are weeks worked. I have a start and end date
on the same row for a project, as these dates are completed I manually
highlight the cells (as though it were a ghant plan) is there anyway
you can link the cells filling with a highlight to the actual dates.

I realise this is probably a whole solution but just wanted pointing
in the right direction.

many thanks Matt
