Re: Find number of unique values in hashby ww (Archbishop) |

This really begs for an "RTFM" answer. Have you done so? If that hasn't (doesn't) make it clear to you, then Data Type: Hash should help (special attention to the content and links in planetscape's offering). In either case, you really need to show that you've made some effort to find your own answer to the problem: where's the code for what you've tried so far and how does it fail? See, please, On asking for helpand How do I post a question effectively?.
