Hi all.

Quick question.

I have several cells - i.e M8 : M12. These cells can contain integers 0
to 10.

I want to be able to design a formula that says - if any cell in the
range M8:M12 contains a 0 then change the value of M13 to say
"INVALID", otherwise it is "VALID".

I'm having a bit of trouble designing this - tried nest IF statements
and formula.

Suggestions appreciated.

Regards
Daz
