Ok Fred, I think I understand, I've now changed the controller to look
like this:
def preview
@advert = Advert.new(params[:advert])
render :partial => 'advert', :object => @advert
end
Before I had: @advert = params[:advert] which I think is what you
mean by it not being an instance of the class.
Now in my partial I can use @advert.title and all works fine.
Thanks for all your help.
