Use of uninitialized value in substitution (s///) at substitute line 6. I don't have any trouble with regex matching using $_ or any varible because I can always say: if $variable =~/\d/ instead of: if(/\d/) which is equivalent to $_=~/\d/; I don't know how to do it with substitutions. any idea? thanks __________________________________ Do you Yahoo!?
