Hi I have a calculated column that counts me no. of weekdays

=(DATEDIF([Registration],[Gate 0],"D"))-INT(DATEDIF([Registration],[Gate 0],"D")/7)*2-IF((WEEKDAY([Gate 0])-WEEKDAY([Registration]))<0,2,0)+1

HOWEVER, a Gate 0 date may not be filled (as the gate 0 has not been reached yet), and I get a NUM! or Name? error. I NEED NUM to be blank or 0 in Reg-G0 calculated column. I have been trying lots of code with no success.

Example data

Project ID Registration Gate 0 Reg-G0
13234 19/02/2022 30/10/2022 180
44954 18/05/2022 #NUM!
69543 14/03/2021 23/05/2021 50
56456 25/03/2021 25/03/2023 522
44368 14/03/2021 14/06/2025 1110

I NEED NUM to be blank or 0.

Try using this formula:

=IF(ISBLANK([Gate 0]),0,(DATEDIF([Registration],[Gate 0],"D"))-INT(DATEDIF([Registration],[Gate 0],"D")/7)*2-IF((WEEKDAY([Gate 0])-WEEKDAY([Registration]))<0,2,0)+1)

It will return 0 if [Gate 0] column is empty.
