exists() will tell you if a hash-table entry has been initialized, even
if its value is undef/null. I would recommend putting
$formdata{view_name} inside square braces in error output to see what is
triggering this. something like:
print STDERR "notempty: [" . $formdata{view_name} . "]?\n";
(which will log to your webserver error log, but will not clobber your
script)
perldoc -f exists should let you know if it's what you really need.

There's a new beginners-cgi list. That's probably the best place for
this kind of thing.
