you can put everything in a textfile with erb  
\<% … %\> will be executed  
\<%= … %\> will be executed and the return value inserted in the file

so the above code looks fine and you should give us some details what  
‘does not work’ for you. get an error message? nothing happens at all?  
the erb tags are inserted ‘as is’ in the output (check source code in  
browser)?
