Got it:
if ($r->param("$param") ne "" ) {
That works.
if (length $r->param($param)) {
should also work.
Note: I don't quote the variable name. It's not needed.
I was suggesting just dropping defined():
if ($r->param($param)) {
That probably works too (testing for "truth"), as long as 0 isn't a valid answer in one of your form fields.
Good luck with your project.

$num is now 10 and that right (only 2 stories this time). Thanx v.much for your time. Dp.

That's gives me all the keys (50) and I have only filled in three stories. I would expect to get 30 in that case but something isn't quite right at 'if (defined($r->param...' because both keys and vaules return 50 which is the total number of possible fields and not simply the ones with a values.
Try removing the call to defined() and just testing to see if the value is true. Or perhaps check for some length(). I suspect you are getting empty strings ( '' ), which are, of course, defined().
