Hi JDB,

It's a bit confusing but try a CF in column M with Formula is:

=AND(NOT(ISBLANK(M3)),OR(TODAY()F3+7,TODAY()M3+7 ))

If that doesn't work then you need to give better details of when cols F and
M
are and aren't populated etc. and also more info all round.

I have a spreadsheet with a start date in column F starting at row 3.
Column
M needs to be highlighted a different colour if the value in F3 goes over
7
days. If there is already a date in column M, then this should be ignored.
However, if the date in column M goes 7 days or more itself, then this
also
needs to be highlighted. Is there a way of using conditional formatting to
achieve the above?
