using simple if + or

Louis Raoul

Hello,

I must be tired, but cannot see what is wrong with this formula.

=IF(OR(MONTH([Planned Entry Date]@row) = 1, MONTH([Planned Exit Date]@row) = 1), "Jan", "Notok")

if either of the 2 dates. are filled, result is Jan

if none or just one is filled, result is #INVALID DATA TYPE

Thanks a lot

Raoul
