hi,

Can someone point me to a good informational page please
explaining about vlookups on my excel sheet or have a
look through this!

Sometimes they work for me and sometimes they dont
sometimes I have headings on my rows should i or not?
does it matter where an array is on the sheet? What
about the source page? Headers or not? and then theres
the 1 that goes at the end of the vlookup after the
column number; true or false? whats that all about?

Rob
