do...), the following should work. might be a better (more efficient)
way to write it...but i'm tired :)
i took the liberty of giving your form fields unique names and ID
values...and removing the onclick event from your submit button
(moving the function call to the onsubmit event of the form itself).
oh yeah, and i went with XHTML (closing all tags, quoting all
attributes, etc) :)

Marta was watching the football game with me when she said,
"You know, most of these sports are based on the idea of one group
protecting its territory from invasion by another group."
"Yeah," I said, trying not to laugh. Girls are funny.
