function clickAction(){
	count += 1;
	console.log("hello "+ count)

My greet route isn't working! What should I change?

app.rb

get "/greet/:name" do
	
	submitted_name = params[:name]
	
	erb :show
end

show.erb

<div>
	 Hello <%= submitted_name %>!
</div>

When I go to /greet/world expecting Hello World!, but I get the following error:

 NameError at `/greet/world`
undefined local variable or method `id' for
 #<Sinatra::Application:0x007f892315d160>
 
 BACKTRACE
 ____________________________________________
 2.		<%= submitted_name %>

8.)

Is this RESTful?

I have a site http://somelist.com that stores peoples names in a list.

I made the following routes

GET '/name/new'			# for showing a new form

GET '/name/create'		# for submiting a 'new' name form,
						# and creating
						
GET '/name/:id/delete'	# for submitting a deleting for a name

GET '/name/:id/edit			# for showing a new edit form

GET '/name/:id/edit/post'	# for submitting an edit
							# from a form

Please give a little explanation.

9.)

What do you think of my controller? I don't even need a view. Why shouldn't I put all this in my controller?

get "/" do
	pageTitle = "myApp!"
	"<!DOCTYPE html>
	<html>
		<head>
				<title>#{pagetitle}</title>
		</head>
		<body>
				<div>
					Hello there!
				</div>
		</body>
	</html>"
end

10.)

Look at my view! This works, but why should I be doing things this way?

app.rb

get '/person/:name` do
	erb :show
end

show.erb

	<div>
		<% person = params[:name] %>
	
		Hello <%= person %>
	</div>
