  That's all fine.

  Which means doing something like:

	if (a) {
	elsif (b) {
	elsif (c) {
	else {

  That isn't what you've configured.  You have a bunch of unrelated "if" statements.

  Do NOT rely on module return codes in order to see whether or not an "if" condition matched.  Instead, use "if", "elsif", and "else".
