Average outage time?
I have a sheet that shows when an item was logged out (i.e. maintenence) and
when it was logged back in. The sheet calculates how long each item was logged out. Now I want to calculate the average outage time for all items listed. I have tried the following functions, the first one errors becase of zero values, the second one is supposed to ignore zero values, but it just doesn't work. =AVERAGE(J114:J164) =AVERAGE(J114:J164)+IF(J114:J164<0,"","") Anything will help!! |

Perhaps this will work:
=SUMIF(J114:J164,"0",J114:J164)/COUNTIF(J114:J164,"0") HTH, Elkar "C.S.Harris" wrote: I have a sheet that shows when an item was logged out (i.e. maintenence) and when it was logged back in.

Average outage time?
=AVERAGE(IF(J114:J164<0,J114:J164))
which is an array formula, it should be committed with Ctrl-Shift-Enter, not just Enter. -- HTH Bob Phillips (remove nothere from email address if mailing direct) "C.S.Harris" wrote in message ...

I think the problem is with my time formatting. For J114-J164, the formula output is [hh]:mm and all cells that don't have info have 00:00, which I can't hide. When I use the formula, I get #DIV/0! or #VALUE!. Anything? Thanks. |

It works fine with time. Your cells must be text rather than numeric is all
I can an think. -- HTH Bob Phillips (remove nothere from email address if mailing direct) "C.S.Harris" wrote in message ...
