Cannot get destroy checkpoint to work

When I run the rails server, open up my app, and get to a "Posts" show
page, I receive multiple errors.  I have been trying to figure them out
for the last few hours.  Everytime I try to fix one thing, I break more
things!  Including the comments checkpoint.  I had it working before,
now it is completey busted.

Can you please take a look.  I imagine the problems have to do
with the following files:

posts_controller (show action)
comments_controller (create action)
app/views/posts/show.html.erb
app/view/comments/_comment.html.erb

It is a mess!  Thanks.
Added :show to the posts portion of the routes file.  Throwing errors.
Added collection syntax to post/show file.  Can view but not save.

Added the collection: @comments syntax to the post/show file.  Now I can
view the comments on the post/show page; however, when I go to save a
new comment, it throws an error and references over thirty files.
Fixed destroy and change
Fixed conflict errors from trying to merge Destroy into Master
