ruby website code ignores function

Edward

When I run the following script as a web page, it ignores the output of
my function and doesn't print the "test2" as if there is a problem with
the function. How can I fix this? I pasted the code below.

Thanks,

#!/usr/bin/ruby
print "Content-type: text/plain\n\n"

3.times { print "Hello World\n" }
print "test1"
print sayHello("Jim")
print "test2"

def sayHello(name)
result = "Hello" + name
return result
end

right, I didn't have ruby installed locally (windows) but I can ssh
onto the site and test it there, THANKS for the tip!
