Please be patient with me. I am new to Perl and am used to working with PHP, so regexs are pretty foreign to me. I am trying to find instance in a string where a lowercase letter occurs next to an uppercase letter. After finding them, I want to put "::" between them. Here's my code: 
$new_type = "BookInstructional MaterialTeaching Guide";
$new_type =~ s/([a-z])([A-Z])/$1::$2/g;
print "$new_type\n";

The output looks shows the string unchanged, but I was hoping it would look like this: Book::Instructional Material::Teaching Guide Any help would be greatly appreciated!
