networkdays and conditional formating

[Guest]

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

=AND(J$2>=$B4,NETWORKDAYS($B4,J$2)<$G4)


=AND(J$2>=$B4,NETWORKDAYS($B4,$J2)<=$D4-1)

Sorry Bob, but this didnt work it returned a message of "you may not use
references to other worksheets or workbooks for conditional formatting
criteria"
