It seems, finally, that the problem may arise from numbers entered as
text in the looked up range, rather than empty cells. Otherwise,
vlookup would return a numerical value if the cell looked up contained a
zero.
So, value/vlookup is the easiest answer.
That, of course, returns an error if the contents of the looked up cell
contain something which cannot be rendered as a number. But, enough
already.

I've just been trying various possibilities with this (using OOo 2.0.3)
and in every case, lookup returns whatever is in the target cell. IMO
this is what I would expect to happen. I may want lookup to return
empty, or with whatever text is in the target cell, or a number.
I tried =VALUE(VLOOKUP(...)) where the lookup returns empty, and I also
get Err:502. VALUE() doesn't like empty/null. So, what is the type of an
empty cell returned by a lookup function? Why isn't it interpretted as
zero or "" depending on context as it is for a direct cell reference?
In the meantime, I think the solution is to split any formula that
contains a problematic lookup so that the lookup is done in a separate
cell, then reference that cell in the formula.
