First off - the code you wrote won't work with Reader, it will only work with Adobe Acrobat.
Second, LiveCycle Designer-based forms are a special type of PDF and don't use AcroForms, they use an XML-based forms grammar.  Therefore, the AcroForms API calls aren't designed to work with them.  You should be using the JSObject bridge code along with JavaScript to access the values of the fields.
