If on the php side, then set the id attribute of the element you want to set focus on, therefore my first reply. If it is on the javascript side, then read a javascript book ;) I would use javascript getElementById() but I don't know if it is cross browser compatible... If you give your form a name, it will also be used for its id, so no need for form[1]. Bertrand Mansion Mamasam
