Use an IF function:

=IF(SUM(N26:O26)=0,"",SUM(N26:O26)

easy I'm sure if you know how - but I don't.

Value of cells N26 and O26 are added together and result shown in P26
if both values in these two cells are zero (£0.00) I want cell P26 to be
blank and not show a £0.00 value

any ideas ??
thanks
