Instance variables created in controller are nil in view

Hi all.

I'm new to RoR and trying to figure out instance variables. I'm trying to put a string in one in the controller and print it in the view. However I'm getting the following error:

NoMethodError in Say#hello

You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.+

Apparently the @text variable remains nil, even though I assign a string to it. Any ideas about what goes wrong?

This is my controller code:

class SayController < ApplicationController   def Hello     @text = 'Hello world from the controller'   end   def Goodbye   end end

This is my view:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/ TR/html4/strict.dtd"> <html>   <head>     <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />     <title>Rails test (say)</title>   </head>   <body>     <p>Hello world!</p>     <p><%= 'testje ' + @text %></p>   </body> </html>

It shows the text 'testje', but there's no output for the @text variable.

It works! Thank you so much. I never would have thought about that.
