if(undefined === formulier)
              {
                  // onestepcheckout
                  formulier = parent.parent.window.opener.document.forms['onestepcheckout-form'];
              }

if(undefined === formulier)
              {
                  // onestepcheckout
                  formulier = parent.parent.window.opener.document.forms['onestepcheckout-form'];
              }

              if(undefined === formulier)
              {
                  // firecheckout
                  formulier = parent.parent.window.opener.document.forms['firecheckout-form'];
              }
