How to pass parameters to function after Suitelet form is submitted.

Hi,

I am new to Suitelets and was hoping someone could help me understand how to pass parameters to a function which runs after a user submits a Suitelet form. Right now I am getting the values in the Suitelet form and can successfully run a function when the form is submitted, however the parameters that I pass to the function come in as null values. What am I missing?

The following is sample code that should illustrate what I am trying to do.

function htmlSuitelet(request, response) {       if (request.getMethod() == 'GET' )     {            var recId = request.getParameter('ID');    var test = 'test 1';             var form = nlapiCreateForm('Test Form');         var testValue = form.addField('custpage_year', 'text', 'Please enter test value', null, null);                             form.addSubmitButton('Submit');           response.writePage( form );        }               //Run the following code when the form is submitted       else{          testFunction(test, recId, testValue);  }  }    function testFunction (test, recId, testValue) {    //All these values come in as null  nlapiLogExecution('DEBUG', 'Test', test);  nlapiLogExecution('DEBUG', 'Record ID', recId);  nlapiLogExecution('DEBUG', 'testValue', testValue);    }
