running total and average of that total after 3 events
 

You will need VBA and/or separate date(s) for each part change. After the 4th
change, presumably you want to average parts 2, 3 and 4?

I want to be able to get an average of how long this part has ben on the
press after 3 consecutive times of being chnaged out
I am using this formula =IF(B8="","",TODAY()-B8)
this gives me a running total of how long the current part has been on the
press.
What I need is a formula that will be able to tell when i enter a new date
in B8 and take the total days from the old part and keep a runnng total until
the 3rd change out occurs and then give an average of how many days he 3
parts were on.
So if say part 1 was on 30 days and part 2 was on 25 days and part 3 was on
40 days the average would be 41.66 days
I ma not sure if whatI want to do is possible but I know there are alot of
creative thinkers here

Thanks for the help

Yes after I enter a new date in the form for part #4 I want it to average the
days that part 1 2 and 3 were on the press
