// Description:
// This parses the string that is generated by the Volusion template generator
// and transforms it into an un-ordered list. (<ul>)
//
// The css needs to be altered for it to display correctly.
//  Hide the value while the new value is being constructed.
 
//  The cart summary is not displayed on every page.
//  Checks to see whether the div exists.
