execute the radio and selective button and return the message on thesame page

[moongeegee]

I have radio button and selective item with executing button on my
javascript, as soon as I press the executing
button, it will display the messages that select on radio and
selective item on another page.
How do I make it display on the same page, perhaps display the message
below the executing button
instead of open another web page and display the return message.

Please help.
Thanks.
