# Need Help With Formula Please

L

#### Langway

Ok, I think I have a tricky one.

A B C
101 1 100
102 0 101
104 0 102
105 1 103
109 1 104
110 0 105

I'm trying to put a formula in column D that will tell me...
If C2 is found anywhere in Column A AND on the same the same row in column B
there is a 1, then 1, if not 0.

Hi,

Try this, It rerurns the 1 or 0 plus if c2 cant be found in column A 'Lookup

=IF(ISNA(VLOOKUP(C2,A1:B6,2,FALSE)),"Lookup Not
found",(VLOOKUP(C2,A1:B6,2,FALSE)=1)*1)

=IF(SUMPRODUCT((\$A\$2:\$A\$100=C2)*(\$B\$2:\$B\$100=1))>0,1,0)

Copy down as desired. Note that if you adjust the range sizes in SUMPRODUCT,
they must be equal in size, and you can only use entire column callouts (A:A)
if using 2007.

This works on your sample data where there are no duplicates in column A and
the values in column B are either 1 or 0:

=SUMIF(A\$2:A\$7,C2,B\$2:B\$7)

If your sample data is "make believe" then try this generic formula:

=--(SUMPRODUCT(--(A\$2:A\$7=C2),--(B\$2:B\$7=1))>0)

Excel 2007+:

=IFERROR(INDEX(\$B\$2:\$B\$7,MATCH(C2,\$A\$2:\$A\$7,0)),0)

Prior versions:

=IF(ISNA(MATCH(C2,\$A\$2:\$A\$7,0)),0,INDEX(\$B\$2:\$B\$7,MATCH(C2,\$A\$2:\$A\$7,0)))
