Not executing OnChange

I took a copy of a production db to my test environment. Made changes but no in the area I am going to discuss.Tha data base is a request for security changes and has upwards of 50 choices of systems.

In production in one of these choices, there is OnChange code ( which works ) to add an extra approver to the form. It works in production. It does not in the test version nor the test version brought back to production. Even in Debugger ( with a Stop command ) it never gets invoked in this test version of the data base.

Anyone have any suggestions as to why it would start to bypass this code.?

Thank You.

Subject: not executing OnChange

what field type is it? If it’s a radio button, checkbox, combobox or listbox make sure the ‘run Exiting/OnChange events after value change’ option is checked on the field properties dialog box.

Subject: not executing OnChange in DialogueBox

I see what you mean about combo, radio , checkbox and lostbox, but this is a DialogueBox and there is no such option in the field properties.Any other ideas?

Thanks a lot.
