    Hi @Ajay,
     
    I think you must add this code in "student middle name" validate method.
     
            field(XX; "student middle Name"; Text[100])
        {
            Caption = 'student middle Name';
            DataClassification = CustomerContent;
            trigger OnValidate() 
            begin
                validate(Studentfirstname);
            end;
        }
    Also don't forget to add Rec.
     If (Rec."student middle Name"<>'') then
    Best regards,
    Mohamed Amine MAHMOUDI

    Hi,
     
    In Middle Name on validate trigger just write -
     
    If (rec.Studentmiddlename <> xrec.Studentmiddlename) or (rec.Studentmiddlename <> '') then 
 Rec.Testfield(Studentfirstname);
    Regards,
    Saurav Dhyani
