Hi,

How to use flash[:notice] in ruby to display error messages.
I have tried it into for loop as follows:-
=============
 for i in 0..(params[:product][:count].to_i-1)
  if params[:product]['demand'+(i).to_s].to_i >
     params[:product]['quantity'+(i).to_s].to_i
	flash[:notice] ="#{params[:product]['demand'+(i).to_s]}  is less than
the
                                      #{params[:product]['quantity'+(i).to_s]}"
  end
 end
redirect_to :action => 'index', :id => @product
============

Here in above code when i get redirected to index action (on
index.rhtml) page I can see only erro rmesage asociated with last flash.
That is in above code i want to store message into flash for all
products for which above 'if' condition becomes true. So that i can
iterate throgh flash & see the error messages related with all products
for which 'if' condition true.

How to do this?????

Thanx in advance.
