In C9, enter formula :

=LOOKUP(9^9,B3:B5/(A3:A5=A9)/(C3:C5<=B9)/(D3:D5>=B9))

Try,

In "Sheet2" E2 formula copied down :

=VLOOKUP(A2,Sheet1!A:B,2,0)

Try,

In F2, enter formula :

=SUMPRODUCT((D2:D20<>"")*(B2:B20<>"")*(C2:C20<>""),A2:A20)

the formula result will return 496

Try,

1] In A15, copied right to B15 and all copied down :

=INDEX(A$4:A$11,MATCH(0,INDEX(COUNTIF(A$14:A14,A$4:A$11),0),0))

2] In C15, copied across right to AG15 and all copied down :

=INDEX(C$4:C$11,AGGREGATE(15,6,ROW($B$4:$B$11)-ROW($B$3)/($B$4:$B$11=$B15)/(C$4:C$11<>""),1))

Maybe,

1] C5, keep empty

2] In C6, formula copied down to C57 :

=IFERROR(1/(1/(INT((ROW(A1)-1)/D$5)*F$5)),"")

Try.............

1] If you have Office 365 or Excel 2019 CONCAT function, use this in H2 and copied down :

=""""&CONCAT(INDEX($A$1:$F2,N(IF(1,IF({1,0},1,ROW(A2)))),MATCH(G2,A2:F2,0)+1)&" ")&""""

Or,

2] If you don't have CONCAT function, use this in H2 and copied down :

=""""&OFFSET($A2,ROW(A$1)-ROW(A2),MATCH(G2,A2:F2,0))&" "&OFFSET($A2,0,MATCH(G2,A2:F2,0))&""""

Bosco, as I stated in my original post, I cannot use the formula you are proposing for column C. I must calculate the difference between the current and previous value for all data points not just the ones which occur on the same day. The question was how to arrange a formula which will allow me to calculate the daily average of those differences, excluding the first value for each day.

Then,

D2, formula copied down :

=SUMPRODUCT((A$2:A$10=A2)*(A$1:A$9=A$2:A$10)*N(+C$2:C$10)/(COUNTIF(A$2:A$10,A2)-1))

Try...………………...

1] In C2, formula copied down :

=IF(A2=A1,B2-B1,0)

2] In D2, formula copied down :

=AVERAGEIFS($C$2:$C$10,$C$2:$C$10,"<>0",$A$2:$A$10,A2)

Similar to Fluff's idea, another shorter formula to obtain the same result.

=0+TEXT(LOOKUP(9^9,C$14:C$37)+1,"[>11]1")

Assume criteria housed in B1:F1 as per below table

In B2, formula copied across to F2 and all copied down ;

=MID(LEFT($A2,IF(C$1="",250,FIND(C$1,$A2)-1)),FIND(B$1,$A2)+LEN(B$1)+1,250)

Further to my posted formula in Post #.2,

Should you wanted to return multiple result in respect of the multiple criteria, you need TEXTJOIN function of which available in Office 365 or above.

Then,

In "Map" sheet F2, array formula (confirm pressing Ctrl+Shift+Enter instead of just Enter) copied down :

=IF($G2="Y",TEXTJOIN(", ",1,INDEX(Lookup!$D$2:$G$52,N(IF(1,MATCH(FILTERXML("<a><b>"&SUBSTITUTE(B2,",","</b><b>")&"</b></a>","//b"),Lookup!$C$2:$C$56,0))),MATCH(C2,Lookup!$D$1:$G$1,0))),"")

and,

Trailing space in B12 should be removed

Regards

In "Map" sheet F2, formula copied down :

=IF($G2="Y",IFERROR(VLOOKUP($B2,Lookup!$C$2:$G$52,MATCH(C2,Lookup!$C$1:$G$1,0),0),""),"")

However,

1] Remove trailing space in B12

2] You have multiple value in cells B99, B243 and B248 of which the above formula will return blank

Regards

To choose the options in column C in the "Report" sheet if chosen in Column B

In "Report" sheet, select C2 >> Data Validation >>

>> Allow : List

>> Source : =OFFSET(List!$B$19,COUNTIF(List!$C$2:$K$11,$B2)+COUNTIF(List!$L$2:$O$11,$B2)*2,,,COUNTA(CHOOSE(COUNTIF(List!$C$2:$K$11,$B2)+COUNTIF(List!$L$2:$O$11,$B2)*2,First_Half,Second_Half)))

>> OK

>> Finish

then,

Copied down

In "Report" sheet, select C2 >> Data Validation >>

>> Allow : List

>> Source : =OFFSET(IF(MATCH($A2,List!$C$1:$O$1,0)<10,List!$D$14,List!$K$14),,1,,4)

>> OK

>> Finish

then,

Copied down

Regards

Try.......

1] "Source table" housed in Column A and B, and "Result table" housed in column D and E

2] In D2, formula copied right to E2, and all copied down until blank:

=IFERROR(INDEX(A$2:A$10,INT(ROW(A2)/4)*3+MOD(ROW(A2),4)-1),"")

Regards

To understand how does a formula work ?

Select your formula, then in the ribbon click "Formulas" >> "Formula Auditing" >> select "Evaluate Formula" >> click "Evaluate", Excel will step through the parts of the formula individually.

Try.............

In K12, array formula (ctrl+Shift+Enter) copied across and down :

=SUM(($C$1:$I$8=K$11)*N(+$B$1:$H$8)*TRANSPOSE($A12:$H12))

Hi Bosco_yip,

Thank you for your reply - I have tried to use the formula you provided but the "Total" rows come up with no value, any chance you.

Those references to column T slightly confuse me, any chance you could elaborate?

Thanks in advance

Display More

I tested your data in "Column T ", and forget bring it back to "Column O"

Therefore,

The formula in O8 should be in :

=IF(C8<>"Total",G8+N8,SUM(INDEX(O$7:O7,MATCH("zz",B$7:B7)):O7))

Sorry tor the confusing

Regards

I think your copy down formula in O8 will give wrong result,

your O25 formula result show in 261, but it should be in 142.

So,

Your O8 formula could be shortly revised in :

=IF(C8<>"Total",G8+N8,SUM(INDEX(T$7:T7,MATCH("zz",B$7:B7)):T7))
