I have had a problem with windows 10 today and so decided to do a spreadsheet of all the stuff I have to reinstall. I figured if I could work out how long it takes to install everything that needs reinstalling I could plan it better the next time this happens.
In the spreadsheet I've got start time, end time, difference (endtime - starttime) and time running total. What I'm trying to do is enter a zero time value for the end time and running total time when the task isn't yet completed.
The spreadsheet so far looks like this A1:A21 = start times B1:B21 = End times C1:C21 = column b - column a and column D = C2+D1 etc...
I've tried the iferror formula but I don't know what to enter when there is an error as it would need to be a zero time value.
Any ideas?
BTW columns E onwards contain the programs I'm reinstalling comments on the installation, passwords etc...
