+A string representing the error code thrown by Bugzilla. This string
+matches the C<error> variable in C<global/user-error.html.tmpl> and
+C<global/code-error.html.tmpl>.
+
+=item C<message>
+
+If the error mode is set to C<ERROR_MODE_WEBPAGE>, you get a reference to
+the whole HTML page with the error message in it, including its header and
+footer. If you need to extract the error message itself, you can do it by
+looking at the content of the table cell whose ID is C<error_msg>.
+If the error mode is not set to C<ERROR_MODE_WEBPAGE>, you get a reference

+
+=item C<vars>
