yes, the regex could be better. When dealing with user input, you should allow whitespace before and after the input. Some common idioms: `s/^\s+//; #remove leading whitespace s/\s+$//; #remove trailing whitespace` [download] Now that whitespace is not a factor, for the match then anchor the search term to front and rear. `/^dog$/; matches dog but not doggie` let me know how you get along with those hints.
