is there a way to communicate between cfinput type=submit and input type=submit or button

Hi,

   Anyone out there willing to help me.

  <cfform format="flash" name="form_flash">

      <cfinput type="submit" name="btnFlash">

</cfform>

<input type="button" value="BUTTON" onclick="chkFlash();">

<script>

     function chkFlash()

     {

          document.form_flash.btnFlash.click();

      }

</script>

This is not a working sample. I want to ask help if there any way to communicate with the cfform flash?Currently, it is undefined with function chkFlash.

Regards,

Jeff
