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
                );

[download]
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.
