Re^2: Find number of unique values in hashby johngg (Canon) |

my %counts={}; I think you need parentheses rather than curlies there. As it is, you are assigning a single hash reference to the hash, which it will then stringify and use as a key with no corresponding value. Also, if you use warnings;, I think you will get one complaining about odd number of elements in hash assignment, or words to that effect. Trying it I get this.
I hope this is useful. Cheers, JohnGG
