The "scalar" he's putting in there is actually an array reference, which is
totally kosher. I've gotten this error many times, and it has always been as
a result of selecting data from a database into a variable (either a true
scalar or an arrayref) and the variable not containing any data when it gets
turned into a param. There would be several ways to fix it, including
setting $rows manually if it doesn't return valid data or some similar sort
of undefined value handling....or other, simpler ways which I can't remember
right offhand. I'll look through my code though and see how I handled it.
In the meantime, while I look for a better way of doing it, try putting this
line after the line at which you define $rows:
$rows = [ { status => 'null' } ] if !$rows;
In this example, the loop "ROWS" will have a tmpl_var called "status" which
will be set to 'null' if $rows evaluates as false. It's a bit of overkill,
but it'll fix your problem.
But seriously Doc, lighten up, and remember that we're trying to help you
out of the goodness of our hearts and our wish to support other developers
using HTML::Template.

Then H-T must be incrediable dumb since that tmpl_var ROWS is in it.
<TMPL_LOOP NAME=ROWS> and Script says ROWS too. I am very much aware of case
sensitive nature of linux.
