Hello,

I'm not sure, but is this question just asking to allow a field with aphabetical characters along with a - and . ?

Of course like davidrw, a name can also contain a '.

unless ( param('Company Name') =~ /^[\w.\'-]+$/) {
   print "Invalid characters in name. Only alphanumeric characters and
+ the following symbols . ' - _  are allowed.";
}
