With help and guidance from this site I have created a gant chart and
which
will change the colour of each cell depending upon activity duration or %
of
activity that has been completed, and it works well.. however how do I
change
the formulas to take into account a 5 day week ie Monday to Friday
The formulas I have are :-

=AND(J$2=$B4,J$2<$B4+$G4)

=AND(J$2=$B4,J$2<=$B4+$D4-1)

Where
J2 = day
B4 = start date
G4 = activity days completed
D4 = activity duration

thanks
