I am an old Excel user who hasn't had the time lately to maintain my skills, so I'm a bit rusty. I'm trying to build a SS to Evaluate new work and time rules for legality. What I need is a formula that will allow me to look back 168 hours from the time a work period begins. If that time is <168 hours, then the hours worked that day would be used in a sum calculation.
These work periods happen on an irregular basis. Any advice is appreciated.
