What I thought was simple addition!?

[ASH2707]

As always, apologies if there is a thread for this alread, but I have no idea of what even to search for

I 'simply' would like cell H14 to add H9 to either H11 or H13, but only the one that contains a value. H11 or H13 will never both have values..

Does this make sence?

Hi, it looks as though it appears to more difficult or complicated than it is - simply put =A9+A11+A13 in you addition cell. If only one of the two cells will ever contains a number it will only produce one result.
