Hi everyone. i have a navigation form and i added a button for a form that contains a combobox and a listbox, a query showed in listbox and filtered by the combobox. The problem is that the form is working fine alone. But when i added it to the navigation form when i press the navigation button for the form it shows a dialoge asking for the criteria of the query. I realy need help because the application is almost done. And there is no codes related to the form. Thank you for your help.
