hi guys,

New to the forum. However been referring to this forum from general google searches for years now.

Seems today im at an impasse for a new problems which is quite specific. I've no doubt heads will be scratching.

I need to be a manner in which I can determine the number of concurrent calls ongoing when a new call is initiated: concurrent - how many active calls are ongoing:

hopefully you can make sense of this example data. I would like to auto-calc the last column instead of visually checking how many calls are active

Excel Facts

What does custom number format of ;;; mean?
Three semi-colons will hide the value in the cell. Although most people use white font instead.
Sort by date Sort by votes
Welcome to Mr Excel forum

Maybe this...

Formula in E2 copied down
=COUNTIFS(A$2:A2,A2,D$2:D2,">="&B2)

Hope this helps

OMG that was quick.

I've pasted that into the workbook and it works a treat. Any chance you could explain how that works please?
Click to expand...

About formula in post 2
=COUNTIFS(A$2:A2,A2,D$2:D2,">="&B2)

Observe that the formula uses progressive ranges, that is the ranges increase when the formula is copied down.
In E2
A$2:A2 and D$2:D2
in E3
A$2:A3 and D$2:D3
in E4
A$2:A4 and D$2:D4
and so on

On each row the value in column B (Start Time) is compared with the values of column D of the current and precedent rows. If the value in D is greater or equal value in column B of current row it means it's a concurrent call. That's it!

Similar solution for mine. I had already worked on the solution when I saw that Marcelo had already posted a reply. Either will work I'm sure.

Thanks both.

If the data was changed like this below to include the date and handsetID, how can i factor in the handset ID as well please?

I've already amended the formula to include the date so it allows me to run across a number of days, now I need to isolate handsets where all the data is on a single sheets:

Formula column D: =COUNTIFS($B$1:$B1,"<="&$B2,$C$1:$C1,">="&$B2)+1
