Hi Paul,

Thanks so much for having a go at this

Could you just double check your formula as I am sure you are almost there
but, in this example, instead of coming up with 886, it comes up with 45, as
in it is finding the tilt of the collector.

Should the array for the MATCH be increased?

Thanks again

Ant

Change your table a little and this will be easy.

10 IE Tilt of collector: 30
11 Orientation of collector: E
12 Answer: 886

Assuming A2 is the Cell with "Tilt of Collector" in it, 30 is entered in C10
and E in C11 the formula for you answer in C12 would be.

=VLOOKUP(C10,A3:I7,MATCH(C11,A2:I2,0),TRUE)

Using Vlookup on C10 finds the correct row and the Match finds the correct
column.

I need to make it so Excel will Lookup a piece of data in the above table
when someone writes in the Tilt of the collector in one cell, and the
orientation in another.

IE Tilt of collector: 30
Orientation of collector: E
Answer (generated by formula) = 886

Can anyone help me with this? I would use IF(AND(OR but that means i would
exceed my nesting limit :(

Thanks!
