Hi Lex,
 I follow your script but it prints out nothing. I guess the inner loop 
is not right. Accroding  to this line :{buttons
    #<WWW::Mechanize::Form::Button:0x3a6702c @name=nil, @value="Go">}

I change the inner loop.I get all the buttons and I am able to set the 
value for @name or @value. But I still have a problem:  I can't print 
the whole line out as
{buttons
    #<WWW::Mechanize::Form::Button:0x3a6702c @name=nil, @value="Go">}

I only print out the some part of it as
 #<WWW::Mechanize::Form::Button:0x3a6702c>



BTW: where can I find some info about relationship among 
form/fields/buttons and other backgrounds ?

Thanks,

Li
