nooB form question

[JWBlue]

I want to use a simple form with a checkbox either on or off and store the
results to a text file, with minimal overhead. Very ignorant about this
stuff so be gentle! I have IIS running (but no front page extensions) on a
windows machine.

Scope: "MyPage.Html" displays form with one checkbox reading default value
from text file (MyFormData.Txt) in same folder. If user changes value of
check box and hits submit it logs those results to MyFormData.Txt
over-writing the previous contents.

What is the simplest way to accomplish? Sample code would be much
appreciated.

Thanks in advance.
