Return date if two columns have the same date

Hi there,

I wanted to use the IFs formula to check if the between 2 out of 6 columns the date matches ( so if they show the same date).
However I do not receive the date 30.01.2007 if I apply the formula even though columns CV and CY have the same date.
Does someone know what I need to do to make it work?

Many thanks in advance for any suggestions.

Regards
Philpi
