Re: Help with If else if

[Michael Stowe <me@xxxxxxxxxxxxx>]

Hmm, what happens with the code I sent you?  Just tested it on my end and
worked exactly as expected.

Try doing a
var_dump($search->plugin->ListViewValue(), $search->facebook->ListViewValue());
to make sure the data being returned is what's expected... you should be
getting string(0) "" returned for both.

Thanks,
Mike
