You are right on the money. I am getting empty strings:
$hash{a1_head} => This is my first headline
$hash{a1_des} => This is my first description
$hash{a1_spllink} => This is my first SPL link
$hash{a1_storyfrom} => The New Scientist
$hash{a1_storylink} => http://www.newsciencetist.com
$hash{a2_head} => This is my second headline
$hash{a2_des} => This is my second description
$hash{a2_spllink} => This is my second SPL link
$hash{a2_storyfrom} => The Lancet
$hash{a2_storylink} => http://www.thelancet.com
$hash{a3_head} =>
$hash{a3_des} =>
$hash{a3_spllink} =>
$hash{a3_storyfrom} =>
...snip
but how do I test for truth?
Thanx.
