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

Using a mouse in Excel is the work equivalent of wearing a lanyard when you first get to college
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?

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
