You put (interactive) after the parameter list (the
argument names), which is empty in your case so should
be the empty list, ().

An interactive function is a "command", which means
you can invoke it from M-x and also bind it to a key.

There are situations where you can have the same
function behave differently when called from Elisp
(i.e., invoked from another piece of code) compared to
when it is used interactively (again, with M-x or
a keystroke bound to that function) - however, as for
me, I don't see a great value in this distinction and
has only rarely used it. Perhaps someone who disagrees
will explain why it is there and what benefits
it brings.

Note that you can invoke non-interactive functions
with `eval-expr' (or `M-:') so it is not like they are
inaccessible to the "interactive" user. (They will
execute noninteractively still, of course.)
