Changed it like who said?  I'm assuming myself, but with no context you 
can't always tell.  Also, stating "didn't work" is often useless to us. 
  What didn't work?  Why didn't it work?  Here it's obvious, you're 
throwing away the return value from your function call.  Either save the 
return value and print it or add the function call directly to your 
original print call.
