Formulae Help for 2 x Dual cell checks

[rick.parry]

Hi, I am in need of some help with what I thought was a simple formulae.
I have attached a sample sheet.
I need cell G3 to display "FALSE" if B3=E3 AND C3=F3. I have entered a formulae, but it does not seem to work unless I double click on the formulae and then click the green tick.

Can someone please let me know why or suggest an alternative solution please.

Many thanks

In G3

=IF(AND(B3=E3,C3=F3),FALSE,"")

Copy down

Your formula is OK but the file is set to manual calculation.

Set it to automatic calculation: Formulas tab>Calculation>Calculation Options>Automatic
