You'll need to post some code.  It's basically done like this:
[code]
app/controllers/my_controller.rb:
class MyController < ActiveController::Base
  def index
    @somevar = 'Hi!'
  end
end

app/views/my_controller/index.rhtml:
<p><%= @somevar %></p>
[/code]
If you want to call a routine in your view, it's best to put it into
the appropriate helper class (that's what they are there for)
[code]
app/helpers/my_controller_helper.rb:
module MyControllerHelper
  def somevar
    'Hi!'
  end
end
[/code]
now your controller/view looks like this
[code]
app/controllers/my_controller.rb:
class MyController < ActiveController::Base
  def index
  end
end

app/views/my_controller/index.rhtml:
<p><%= somevar %></p>
[/code]
