I’m using Mechanize to submit a form and it points to  
my ‘form.submit’ line and says “both of body argument  
and HTTPRequest#body set” as an argument error in  
http.rb in function set\_body\_internal

Can anyone point me to what exactly this ArgumentError message means,  
and how it might have come about.
