=IF(C3=0,NETWORKDAYS(A3,Holidays!A1,Holidays!A3:A 30),NETWORKDAYS(A3,C3,Holidays!A3:A30))

Try this:

=if(A3="","",NETWORKDAYS(A3,IF(C3=0,Holidays!$A$1, C3),Holidays!$A$3:$A$30))

Here is the function I am using.
=IF(C3=0,NETWORKDAYS(A3,Holidays!A1,Holidays!A3:A3 0),NETWORKDAYS(A3,C3,Holidays!A3:A30))
I have two questions first is there a way when coping to new cells to
prevent excel from changing the reference numbers. It changes Holidays
sheet
references but they don't need to change.
Second this formula is referring to =NOW() in Holidays!A1 but if there is
nothing entered in A3 it gives a long number so is there a way it insert
another IF so that it shows nothing, like =IF(A3=0),"",.
