Try this, Using the %{} make declaring a string over multiple lines  
easer and then you can also use direct #{} substitution for the  
variables which removes all the ‘+’ and ‘"’ characters.

@return\_string += %{

  
#{company.street\_addr}  
#{company.city}  
#{company.state}  
#{company.pin}  
#{company.branch}  
link\_to\_remote ‘EDIT’, :update =\>  
‘detail’, :with =\> “company\_id=#{company.id}”, :url =\> { :action =\>  
‘edit\_comp’ }  
}
