I want to add “.cvs” at the end of a name,and use the following  
sentenses:

namelist.each do |name|  
name = name +’.cvs’  
end

but error message is :

test2.rb:43:in `+': can't convert String into Array (TypeError) from test2.rb:43 from test2.rb:39:in`each’  
from test2.rb:39

What’s wrong with it? how to fix it?

thanks!

If your objects in namelist are enumerable objects, then you must  
further take it apart.
