You could do a regex to check that there aren't any non-digit characters. Just replace your elsif conditional with this:

elsif ($salt !~ /\D/) {

But looking at your example, do you want something a little bit more specific? Do you want only numbers in a particular range?

[Lady_Aleena]: ... Does it have to be that hard and complex to use to do a search on Netflix?
