Subject: Re: Form and hidden variable question
The source you see is what is actually fed to the browser (typically,
anyway). The JS changes what's in the browser's memory, but not what it
thinks the source is. This is not really any different from the fact
that, when you type something into a textbox, it doesn't change the
source display.
It sounds like the JS is working correctly. Check the value of the
contents on the action page to see if what you want is really getting
through.
