Help for navigation- set_parameter

Question

Hi
I am creating BSP application in which i am supposed to pass the value of a htmlb inputfield to another bsp page. I am able to get the inputfield value for that page in the   oninputprocessing event but not able to pass it to fibal page,
  CASE event->id.
    WHEN 'Display'.
      DATA: reportname TYPE REF TO CL_HTMLB_INPUTFIELD.
      reportname ?= CL_HTMLB_MANAGER=>GET_DATA(
                          request = runtime->server->request
                          name    = 'inputField'
                          id      = 'myInputField1'
      IF reportname IS NOT INITIAL.
        <b>report_name = reportname->value.</b>
      ENDIF.
      navigation->set_parameter( 'report_name' ).
      navigation->next_page( 'DISPREPORT' ).
    WHEN others.
  ENDCASE.
The htmlb controls for these are as below,
      <htmlb:inputField id        = "myInputField1"
                        type      = "String"
                        invalid   = "false"
                        width     = "200"
                        visible   = "true"
                        disabled  = "false"
                        required  = "true"
                        maxlength = "30"
                        size      = "50"
                        design    = "standard" />
      <htmlb:button id            = "Display"
                    text          = "Display "
                    onClick       = "Display"
                    tooltip       = "Displays Report"
                    width         = "60" />
Now in the final page  i must get the <b>report_name</b> value which has been declared as a string in the page attribute of default BSP. Further i have it declared the same as auto in final page. Still i am not able to get the value.
I am new to BSP and any help is appreciated.
Thanking you in advance.
Thanks

Hi Raja,
Thanks for the warm welcome, sorry to say it is not working.
The report_name is a page attribute of default BSP. I am not able to get it in the result page.

<b>and in oninitialization of result.htm</b>
