Count blank cells between related cells in a range

[germandiazm]

Hi,

I need to count the blank cells between row on column A that matches the date in cell G2.

So when I update the date on cell G2, the result of the formula will show how many days left until harvest commences.

So result in C2 should be 3, and in E2 should be 15.

[TABLE="width: 570"]
<colgroup><col><col span="7"></colgroup><tbody>[TR]
[TD="align: right"][/TD]
[TD][/TD]
[TD][/TD]
[TD][/TD]
[TD][/TD]
[TD][/TD]
[TD]

Thank you for your help!

Thanks Peter,

The first formula worked really well, I'll just have to modify it to work even when the date in G2 is not yet on the array or when there's no value on the column, but that is just some tweaking I'll need to play with.

I couldn't make the second option work =MAX(AGGREGATE(15,6,$A4:$A34/(B4:B34<>""),1)-$G2,0), it returned a 0 value in all cases.


Thanks

... even when the date in G2 is not yet on the array ..

For the sample data in post 10, do you mean if G2 is, say, 5 August 2018?
If so, what do you want the formula to return in that case?

... or when there's no value on the column

What do you want the formula to return in that case?

I couldn't make the second option work =MAX(AGGREGATE(15,6,$A4:$A34/(B4:B34<>""),1)-$G2,0), it returned a 0 value in all cases.

I thought this might be how that formula would work. In columns B, E & F the earliest date in the column is before the G2 date, so i thought you might not want negative values showing in those columns. What do you want in a circumstance like those columns?

Is when I'm preparing the info for the next couple of months, so G2 could be 15/July/2018 but the sheet is for the month of September.

What do you want the formula to return in that case?

A blank cell

I thought this might be how that formula would work. In columns B, E & F the earliest date in the column is before the G2 date, so i thought you might not want negative values showing in those columns. What do you want in a circumstance like those columns?

Cell	Formula
B2	=MAX(AGGREGATE(15,6,$A4:$A34/(B4:B34<>""),1)-$G2,0)

<tbody>
</tbody>

A 0 instead of a negative is perfect, but when I tried the formula it returned 0 to all cells, including the ones that should have been positive values.

That didn't tell me what you want returned in that circumstance.
What is wrong with these results? (Note also that this formula with MAX in it is not returning all 0 values)

OK, so we'll just add an IFERROR to it

Here it is again, seems to me to be what you are asking for.
- Number of days when the first value in column is after the G2 data (columns C & D)
- 0 When the first value in the column is before the G2 date (columns B & F)
- Blank when there is nothing in the column (column E)

Hi Peter,

Thank you so much for your help, that is perfect!

Just in case, in my previous message I didn't mean that the result on your example was wrong, I meant that when I used it I was getting the wrong result (I had made a mistake in the formula).

Again, thank you very much!

German.
