Match 2 cells to produce a third value

Hi,

I have 2 sheets of data one for data the second for input and calculations.


SHEET 1 (Data)
HEADINGS - FROM / NUMBER
A / 81
C / 99
E / 01

SHEET 2 (Input & Calculations)HEADINGS - FROM / TO / FROM val / TO val

I want to be able to stick "A" in Col1 (FROM) and the number 81 to automatically appear in Col3 (FROM Val)


I am unabel to use LOOKUP as my Pocket PC doesen't recognise it.. VLOOKUP and HLOOKUP are ok though, I just can't seem to get them to work for me
