do not run formula if cell is blank
I am a new Smartsheet user. I have search some previous inquiries on this topic and tried the suggestions but I cannot seem to get it right.
What do I need to add so the formula will not run if the check-in and check-out dates are blank?
=NETDAYS([Check-In]1, [Check-Out]1 - 1)
Thank you so much for your help.
