Hello,
I am wanting to create a cell that will sum up any time gaps over 10 minutes on a list and highlight the gaps.

Here is an example of the cells.

Activity_Time
11/21/2005 11:08
11/21/2005 11:17
11/21/2005 11:17
11/21/2005 11:21
11/21/2005 11:25
11/21/2005 11:28
11/21/2005 11:30
11/21/2005 11:38
11/21/2005 11:39
11/21/2005 11:59


On this list there would be one gap totalling 20 minutes. The 11:39 to 11:50 gap. Everything else would be ignored being under 10 minute gaps.

Is there a way to create a cell next to this that would highlight these gaps and then sum the total string of gaps??


any help would be appreciated.
thanks!!

Say your data is in the range A1:A11, with the heading in A1. In B3 enter:

=MINUTE(A3-A2)>10

and copy down to B11.

Select A2:A11 and choose Format|Conditional Formatting. Condition 1 Formula is:

=OR(B2,B3)

click Format, choose what you want and click OK twice.

One more question if I may.

I have taken the cells that say TRUE and converted a cell to read the total number given.

=MINUTE(B3-B2)>10 This is in cell Column C

=IF(C2,B3-B2) This is in Column D

Column D is now returning either FALSE or the time gap in hh:mm:ss. I am trying to total the number of minutes by summing them but it isnt working. Its seeing the formula instead of the number.

Any idea how I can fix this?

This formula:

=C2*(B3-B2)

will return the number of minutes or zero. You can sum that column and format as [mm]:ss or you can multiply the sum by 1440 to get the minutes as a number.

I'm sorry if i'm being a pain, but now I have another problem to deal with.
The above formula works great! Thanks, however now I am running into a problem of the total not summing based on a cell that has #NUM! in it after the last gap is calculated. I want to have several extra cells there so I can input the list of times. The rows will vary. Any way to not include the "#NUM!" text from the whole sum?

thanks

Sorry I started the new thread. The previous question to get to where I am was answered and I thought this was lost in the shuffle. My appoligies.

The actual formula that is returning the error is =MINUTE(A13-A12)>10
It works up until the point where the string ends.

A14 in this case would not be a number to actually subtract A13 which returns the error. I'm wanting to keep the string open.

As it is i'm having to adjust the actual columns to sum meaning I have to sum A1 to A13. I would like to automatically sum A1 to A200 even though I may not be utilizing all 200 cells. Ignoring the cells without numbers would work but I cant figure out how to format it?

Again, I'm sorry for creating the new thread.. Thank you.
