Hi all ,
Can you tell me what's wrong with this formula :
COUNTIFS({Catégorie_courrier}; ="Permis"; OR({COURRIER_Réponse}; ="Oui"; {Traitement_demande}; ="Oui"))
It returns the error message : " INVALID DATA TYPE " .
As {Catégorie_courrier} , {COURRIER_Réponse} and {Traitement_demande} are 3 ranges each corresponding to a drop-down list column .
The corresponding columns are " Catégorie " , " Réponse" and " Traitement " and I want to count the number of rows with : " Catégorie " column taking the value of " Permis " , and the " Réponse " column taking the value of " Oui " or the " traitement " column taking the value of " Oui " .
Can someone help me ?
