Hi, For some reason this validation:

OR(ISBLANK ( Closed_Won_Reason_1__c), ISBLANK( Closed_Won_Reason_2__c ), ISBLANK(Closed_Won_Reason_3__c),ISBLANK( Signer__c ),ISBLANK(Current_Add_ons__c ) 

&& ISPICKVAL( StageName , "Closing"))

Is resulting in an error message for my users in which they can not edit any date fields in the account without the error message popping up and not allowing them to save. Does anyone see how that could be possible?
