Hi Expert's

is it possible to write a vlookup formula...so as you drag the formula across from A2:Z2 the column reference changes to the next one along..

so =if(isna(vlookup(d3,d45:j55,3,0)),"",(vlookup(d3:j55,3,0)))
So the 3 changes. ..

That is the default behavior. Insert the formula in one cell, as you drag it vertically the column references will get updated.

No, it can be done and in fact it will be done automatically when you drag your formula vertically.

When you have cell references within a formula they will change as you copy/drag across/down unless you append the row or column reference with $.

However, you are referring to the offset value in the lookup formula which is not a cell reference, it is just a number.

That offset number can be calculated in a number of ways.

COLUMN() - will give the column number of the column in which the formula resides, can be useful if the source data and the lookup based data have the sqame column layout. If the layout is basically the same but slightly different column poisitioning, you can use COLUMN()+n where n is the number of colummns different.

MATCH(value,range,type) - can be used to match a column header. The value would refer to the column header of the destination data, the range would be the row of headers in the source data, type would be 0 to find an exact match but that does mean that the column headers do have to match exactly.

To stop the default column changes, you can amend your formula to:

 =IF(ISNA(VLOOKUP($D3,$D$45:$J$55,3,0)),"",VLOOKUP($D3,$D$45:$J$55,3,0))

As you're using Excel 2007, it can be simplified further to:

=IFERROR(VLOOKUP($D3,$D$45:$J$55,3,0),"")

OK, the question was about changing the lookup column from 3 to 4 to 5 etc not the lookup range.
The asker seems to have found the solution in the Column() function.

I would tend to use teh following (dropping the isNA):

=IFERROR(vlookup($d3,$d$45:$j$55,column(C1),0),"")
