vlookup with if statement together

[fruitchunk]

I need help to do a vlookup with if statement together
Sheet 1 - Column A: Dates, Column B: Names:, Column C: Control Numbers,
Sheet 2 - Column A: Dates, Column B: Names, Column C: Code Numbers,
In Column D on sheet 2, I want to see the Control Number for the specific
Name and specific Date.

This is what I have in D1 =IF(A1=Sheet1!A:A,VLOOKUP(B1,Sheet1!$A$1:$C$100,3))
Instead of getting the Control Number I get FALSE
What am I doing wrong? Can you please help?

Try like this in d1 copied down

=LOOKUP(2,1/((A1=Sheet1!A$1:A$100)*(B1=Sheet1!B$1:B$100)),Sheet1!C$1:C
$100)

Try this array formula** :

=INDEX(Sheet1!C$1:C$100,MATCH(1,(Sheet1!A$1:A$100=A1)*(Sheet1!B$1:B$100=B1),0))

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER)

Now it gets a bit more complicated. I have to use Start Date and End Date on
sheet1

Sheet 1 - Column A: Start Date, Column B: End Date, Coulmn C:Names:, Column
D: Control Numbers,
Sheet 2 - Column A: Date, Column B: Names, Column C: Code Numbers,
In Column D on sheet 2, I want to see the Control Number for the specific
Name and specific Date if the date on sheet2 either matches the start or
end date or is between the dates.

Thanks

Oh yeah, it always gets more and more complicated!!!

Try this array formula** :

=INDEX(Sheet1!D210,MATCH(1,(A2>=Sheet1!A2:A10)*(A2<=Sheet1!B2:B10)*(B2=Sheet1!C2:C10),0))

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER). Hold down both the CTRL key and the SHIFT
key then hit ENTER.
