Acrobat Form Submit error: changes VALUE="true" to "0"

[Douglas_Maus@adobeforums.com]

I wrote an HTML page with a form.
In the form I had many inputs as in:
<INPUT TYPE="radio" NAME="Q1" VALUE="true"> and
<INPUT TYPE="radio" NAME="Q1" VALUE="false">
(among other inputs).
I used Mac Adobe Acrobat Professional 6.0.0 to convert this page to PDF.
I was able to have some people fill out this form in the PDF file and submit
the data (as HTML) to the script on my website.
Most people's submissions worked correctly, e.g.
....Q1=true&Q2=false&Q3=true...
Oddly, when one person submitted the form, all the VALUE="true" and VALUE="false"
were replaced by 0 and 1 (respectively), as in:
....Q1=0&Q2=1&Q3=0...
Makes sense (0=true, 1=false in most computer languages). :)
Needless to say this throws off my entire data processing automation scheme.

Does anyone have any ideas why Acrobat is changing my HTML FORM VALUES
behind my back?
Is this a known bug? Should I have known better than to use VALUE="true" and "false"?
Seems like this shouldn't be the first time people use those VALUEs.

(This is a medical survey and due to privacy constraints,
I can't get any additional info about the client other than
it was Windows XP and Internet Explorer on a computer about a month old.
So I don't know which Acrobat Reader version it was running, if it was a plug-in, etc.)

Thanks for any help.

I don't know, but it seems clear that the easiest way to prevent this is to use different values.
