[nicci]

Hello,
I installed the plugin as per instructions in
http://dry.4thebusiness.com/?document=3 and
installed it through
ruby script/plugin install http://rfpdf.googlecode.com/svn/rfpdf
and writing a sample code from http://wiki.rubyonrails.org/rails/pages/Rfpdf
worked fine but when looking for more HTMl related funtions i movd
back to http://dry.4thebusiness.com/?document=3 and viewed the
sample PDF source code and tried to work it out i was unable to..the
error might be in TCPDF.new() but i could not trace a reason for the
same as in my sample code we use FPDF.new(0.
someone plz help me out, how to solve it out..i also looked for in
google code as per a previous post but could not find as such..plz
help

thanks..
