This is what my 2 sheets in Excel looks like, I need to do a vlookup on the 2nd page that looks up the table in the first sheet, and prints out what is in Column C if column A and B match. So the match 0 and 100001 would display 855.71.

I’ve tried concatenating colum A and B together and matching that using this formula:

```
=VLOOKUP(A3&B3,Sheet1!$A$1:$D$8,3,FALSE)
```

But i just get the #N/A error, any help would be great.

You’ll have to concatenate in a new 4th column on Sheet1 to use Vlookup in this manner. Instead though, you could use `sumifs()`

since your lookup is a number and the lookup values appear to be unique:

```
=sumifs(Sheet1!C:C,Sheet1!A:A,A1,Sheet1!B:B,B1)
```

As an alternative, if the values in C are not numerical and you don’t want them summed, you could use a combination of `index()`

and `sumproduct()`

where `sumproduct()`

will provide the row number on which a match is found and `index()`

will retrieve the value from that row:

```
=index(Sheet1!C1:C500, sumproduct((A1=Sheet1!A1:A500)*(B1=Sheet1!B1:B500)*Row()), 1)
```

That’s ugly but it will get you out of having to make a superfluous column just for concatenating a key. Note that this will only work if there A and B are unique. If there are more than row where A and B are the same, then the ROW() returned will be summed and the lookup will be incorrect.
