Well, fixing the typo where you build the key for the last assignment
would help with your immediate problem. *HOWEVER* You're still
solving the problem in a wrong-way.
*EVERY TIME* you see a list of variable names (or hash keys) of the
form foo1 foo2 foo3 foo4 that should be a GIANT WAVING RED FLAG that
your data model is lacking.
Lacking is not strong enough a word.
How about "is pessimally awful."
"...deserves never to see the light of day."
Perl has a built in data type highly suited for a series of data
indexed by a monotonically increasing integer. The List.
my @keyword = split ( /\//, 'something/wicked/this/way/comes' ) ;
If you like the refence version of it
my $keywords = [ split (/\//, 'something/wicked/this/way/comes') ] ;

Computer software consists of only two components: ones and
zeros, in roughly equal proportions. All that is required is to
sort them into the correct order.
