Formula to count the number of different dates in a colummn

[neilsowerby]

My data table contains multiple entries for each member of staff and shows the number of hours worked on each day and on what activity. Therefore there can be more than one row for each day.

In a summary for each member of staff I need to count the number of days. Formula to be entered in Cell B25.

How Do I,

Again the reference to A24 will not progress to look for "Y" & "Z" in A25 and A26?

The answer is correct in A24.

 

[Jonmo1]

$A$24 should be changed to $A24

Again I'm not really sure what you are trying to do...

Is this what you are after?

How Do I,

Exactly right. But I cannot get the cell references $A24, $A25, $A26 to increase down the rows in the table. Reference is fixed at $A24.

 

[Jonmo1]

Is calculation set to Auto?
I'm guessing it was set to manual, then you changed it to auto.
That's when Excel Froze up on you...


How are you entering the formula(s)
Are you :
1. Entering it in 1 cell with CTRL + SHIFT + ENTER
THEN filling down?

Or
2. Entering it in ALL cells at the same time with CTRL + SHIFT + ENTER?

2 will not incriment A24.

 

[neilsowerby]

Thanks jonmo1 and How Do I,

Problems solved. I was entering the formula in all cells at the same time.

Thanks again Guys.

Nice one, I'm pleased you got it sorted.
