I have 2 warnings before output. What is the problem?

Hello = “Hello, guys!” Hello2 = nil Hello2 = Hello puts Hello2 puts Hello

OUTPUT________________ Variables.rb:7: warning: already initialized constant Hello2 Variables.rb:5: warning: previous definition of Hello2 was here Hello, guys! Hello, guys!

Variables that begin with a capital letter are assumed by ruby to be constants, so you get a warning if you try to change the value. Using Rails it best to stick to the conventions, so variable names are of the form name, another_name and so on.
