Brian,

Thanks for the ideas. I'll use It.

When I've checked my HTML code like you wrote it, I found
MY error. It's not Sinatra the problem.

I use a helper but in this helper I use a session variable
like 'session[:my_data]'. The helper's method is called in my
HTML code and the session variable is not evaluated.

So, be careful when using var. in helper's method.
