Subject: problem with variables

Hi.

I've a problem with variables.
I define a global variable outside a method and then I use this variable 
in a method. And thats my problem. I can print the value of the variable 
but in the line with the eval() the place holder (#{temp}) is not 
replaced and the output is empty. But why.

Can anybody help me?

<code>
#!/usr/bin/ruby

$temp = "Hallo"

def test()
   puts $temp                    # -> Hallo ... all is okay
   test = "#{temp} World"
   puts eval( '"' + test + '"' ) # -> ... nothing ... but why?
end

print "Content-type: text/html\n\n"
print test()
</code>

bye
