With ie 7.0 everything’s fine, but with firefox 3.0:
When I select a category, the two ids are replaced. After that, I want
to select a description, but it doesn’t send a request. However,
selecting another category does. The same the other way round, i.e.
when I begin with selecting a description.
The source code is of no avail, because with both browsers it never
changes whatever I select.
Any idea?
Thanks
