When you declare the @VARIABLES array, you are filling it with the literal strings '$colPeriod', '$colCode', '$colName', '$colHandle', '$colDate', '$colFrom', and '$colTo'
Perhaps that line should be 
my @VARIABLES = ($col."Period", $col."Code", $col."Name", $col."Handle
+", $col."Date", $col."From", $col."To");

Your BuildHeader() function will populate the %Header hash, but I suspect it isn't doing quite what you want. If you add 
use Data::Dumper

to the start of your program, and then after you have called BuildHeader(), add 
print Dumper(%Header);

you should see what %Header now looks like.
