Hi pekkhum,
There are indeed many ways of doing this, avoid using Switch.pm as that is too buggy.

What I normally do in this situation is create an HTML drop down like so (which takes away 'true' user input like a text form):

<select name="foo"> <option value="">Please make a selection <option value="first">First <option value="second">Second </select>
Then in the script have a hash pointing to functions:
my $doit = $q->param('foo'); my %functions = ('first' => \&one, 'second' => \&two );
This can then be called by dereferencing the sub:
&{ $functions{$doit} };
Obviously it would probably be wise to have a default to act as an error trap but hopefully the above might give you some ideas.

Another alternative would be to look at CGI::Application which is a handy tool for this kind of thing.
