ok, I added this piece of code...
in my add to cart method, where @remaining was defined in my show section. It's not running in this cart method when the condition is met.
-- if @remaining == 1
# put some conditions around this @remaining == 0?
Product.update(params[:product_id], :funded => true)
Cart.where(:product_id => params[:product_id]).update_all(:processing => true)
#
end
in my add to cart method, where @remaining was defined in my show section. It's not running in this cart method when the condition is met.
I can try outputting the value, and see what I get.

If you're calling other methods during that show request, the instance variable will be available. If you want to access it from another method that responds to a different request, it won't be set. You can also use this instance variable in any views resulting from the show method.I hope this was clear enough...Tamara
