Well firstly, this has nothing to do with TT!

And that is exactly what you would expect, no? If not, you need to read
up about HTML forms.

You're using CGI.pm or some replacement, yes? (You don't say, so I have
to guess :( )

So if you look in its perldoc, it says:

"Pass the param() method a single argument to fetch the value of the
named parameter. If the parameter is multivalued (e.g. from multiple
selections in a scrolling list), you can ask to receive an array.
Otherwise the method will return a single value."

So it is behaving as it's supposed to, no? And what you need to do is
assign to an array instead of a scalar, to get the list of values.
