Emphatically SECOND Boris' advise, but also note, running perltidyed vers provided by Arunbear, with warnings ONLY (strict turned off to omit the complaints "...requires explicit package name..."), produces this: 

C:\_wo\pl_test>perl -c amp.pl
Name "main::index_loc" used only once: possible typo at amp.pl line 64
+.
Name "main::link_target" used only once: possible typo at amp.pl line 
+171.
Name "main::wd" used only once: possible typo at amp.pl line 74.
Name "main::docroot_web" used only once: possible typo at amp.pl line 
+156.
Name "main::high_results" used only once: possible typo at amp.pl line
+ 152.
Name "main::page_script" used only once: possible typo at amp.pl line 
+153.
Name "main::grains" used only once: possible typo at amp.pl line 63.
amp.pl syntax OK

Also new, so this may be beside the point, but at a minimum, means you have done (been there, done that) a lot of work that doesn't have a payoff
