I haven't expressed my problem very well.

I am making a downtime tracking sheet (based on someone elses template)

Downtime is entered according to three criteria. Process, Machine, Fault.
I would like to hvae have a seperate sheet for each month, but I don't know how to change the Sumif formulas to gather data from each monthly sheet and and give a total next to the Process, Machine and Fault lists.

If someone good help me out I would be most appreciative. But please, use small words, I'm very new to this.

Thanks
