The error message means that you have to install the module HTML::TokeParser::Simple.	[reply]

Did you install the HTML::TokeParser::Simple module? See Installing Modules from the tutorials section of this site. Martin	[reply]

The error message is telling you that perl can't find the module you are trying to use. Do you have `HTML::TokeParser::Simple` installed?	[reply] [d/l]

A thimble-ful of additional explanation might be useful here... When you `use` or `require` any external module, such as (in this case) `HTML::TokeParser::Simple` Perl must search for the appropriate module. As you can see, the package-name above strongly implies that there's some kind of hierarchical, directory-like structuring going on, and in fact this is so. Perl will be looking for `HTML/TokeParser/Simple.pm`. But where will it look? The short-and-incomplete answer is that it will iterate through a list-type variable, `@INC`, looking in each of these places for the directory/file in question. There are several ways to determine what's in that list, including `use lib` directives, the `PERL5LIB` environment-variable, and a predefined starter list which is built-in to Perl itself. You can use the command, `perl -V` (note the capital “V”) to display, among other things, the contents of this list. Under your circumstances, I would say that it's fairly certain that the module you're looking for is not yet installed anywhere. There are, as you will soon see, several alternatives for how-and-where you may do so.	[reply] [d/l] [select]

The `@INC` list is given as part of the error message, so it's pretty easy to see what's currently in the list.	[reply] [d/l]
