Hello Charlie, Yes, your answer is good. We must convert the Gambas boolean(True or False) to MySQL Logic(1 or 0 (not y or n)), otherwise Gambas write always "FALSE" in the field. (Never True even if Checkbox.Value = True) Perhaps a bug ? -"Why are you calling my name ?" Because i think that you have to answer me to my first question. No ? Avec toutes mes amitiés. °~Jacky~°
