Ruby website code ignores function

ruby-talk
1

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.

=====================================

#!/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

as with cgis in any language, always, always, always make sure they can run
from the command line, preferably as the webuser. doing so in this can shows:

     harp:~ > cat a.rb
     #!/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

     harp:~ > ruby a.rb </dev/null
     Content-type: text/plain

     Hello World
     a.rb:6: undefined method `sayHello' for main:Object (NoMethodError)

in ruby, functions must be defined before they are used.

kind regards.

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