Hi


What I need to get is the first date when a number appears in column M which is 9-Jan-17 (min date) and the second is the last date a number appears in column M which is 3-Feb-17 (max date) Also it must also fall between the dates that are in columns LL and LM.


Any idea how I get arrive to the answer?


Thank you
MM

I'm curious and wanted to know something if possible. The formulae is dependent on the lowest date and the highest most current date. The current date will always be the first date listed so my question is can/how would the formulae look like if we took out the last section?


[TABLE="class: gmail-cms_table, width: 0"]
<tbody style="border-collapse: collapse; border-spacing: 0px 0px; font-size: 13px; margin-bottom: 0px;">[TR]
[TD]P1[/TD]
[TD]=AGGREGATE(15,6,B2:B30/((M2:M30<>"")*(B2:B30>=LL2)*(B2:B30<=LM2)),1)




can we remove this section
*​
(B2:B30<=LM2)​
) and if yes what would it now look like? I've tried a few variations but can get it to return the same value. ​

​
Thanks ​

I don't quite understand that. In my layout above, which cell(s) contain what you are describing as the "current date"?

Hi Peter

I was able to work it out. What I realized after seeing your formulae was that I only needed to reference the 1 date and not both. So I changed the formulae to
=AGGREGATE(15,6,B2:B30/(​
(M2:M30<>"")​
*​
(B2:B30>=LL2)​
1) Since my dates are always in order and the data I want to use is 5 years from the most current date and your formulae references this date as => so no need to make the formulae any longer than needed.


I do have a question, I tried a few variations but I was unsuccessful. What if I used the "same" formulae
=AGGREGATE(15,6,B2:B30/(​
(M2:M30<>"")​
*​
(B2:B30>=LL2)​
,1)​
But rather than getting the Largest/smallest date that we instead get the average price in column M based on the date being => in cell LL2?

I currently use DAverage function and I curious if theirs a different way to get the same results.

Thanks again!
MM

Is this what you mean?

=AVERAGEIF(B2:B30,">="&LL2,M2:M30)
