Hello guys
Actually keyfield,keyfield2,focustext are all properties in the a form class that I designed and on the actual form.scx I have the correct keyfield names and the textbox that I want the focus to be set to after saving (focustext) all type in correctly in the forms properties. I don't have any error handling active with the project as yet. If I can't find a solution to this issue I will remove the beforesave() method and place the code directly at the top of the save() method. If the thisform.keyfield2 is empty I would simply issue a return so as to get out of the save() method. Does this may any sense?
