// To use this file, add the following tag inside your HEAD tag: (make sure that src= points to this file)
//
//
// To append the URL arguments k and v to link URLs:
// the links must have their id attribute set to TRACKING_X where X is a number between 1 and 5
// For example: online request form
// inside your BODY tag, add an onload= attribute and call appendToHrefs, passing in a default keycode like this:
//
//
// To set form variables from URL arguments:
// inside your BODY tag, add an onload= attribute and call setFormVariables like this:
//
// these form variables can be set:
// document.forms['FORM_TRACKING'].memberArea
// document.forms['FORM_TRACKING'].memberNum
// document.forms['FORM_TRACKING'].formCode
// document.forms['FORM_TRACKING'].leadID
