First you must work out which bit is not working (that is always the first thing to do when s/w does not work). Look in development.log to check that parameters are being passed correctly and the correct action is being called, if that is ok then you can put debug code in the controller to work out what is going wrong. puts statements in the controller will appear in the server terminal window.
