VLOOKUP returns #N/A if the value does not match. ISNA is just a function
that tests for #N/A.

So in logical terms the formula is saying

Do the VLOOKUP and if the result is no match (ISNA) then show "", else do
the VLOOKUP again and show the result.

Brilliant! Could someone just explain to me how it works? - I haven't used
Vlookup before, and what does ISNA stand for?
Thanks

You're missing a paren. Try

=IF(ISNA(VLOOKUP(C4,'Other Committees schedules'!C4:D3500,2,FALSE)),
"", VLOOKUP(C4,'Other Committees schedules'!C4:D3500,2,FALSE))

With C4 being the 1st reference number in column C and D3500 being the
last
price refernce number...
Any suggestions?
