Sorry, must be being a bit thick here. Tried that and cell stays blank all
the time.
My formula is =vlookup(A1,Items,2) Items being the referecne chart on
sheet 2,
Any more on this thanks.

It depends exactly on how your formula works. The normal approach would
be:

=IF(ISNA(your_formula),"",your_formula)

But if the error is caused solely because of the reference cell being
empty (assume this is A1), then you could also try:

=IF(A1="","",your_formula)

Hope this helps.
