Woo hoo! :-)
The Net.Connection debugger did it and no one would've guessed what the
dataProvider looked like!
where I had
<arg1>{kingdoms_cb.selectedItem.label}</arg1>
in my remotingObject's method . . .
. . . I needed
<arg1>{categories1.items[kingdoms_cb.selectedIndex].KINGDOM}</arg1>
thanks for all the help folks
as usual the whole exercise has helped get a better picture of it all anyway
:-)
