      And does the sub receive the file correctly? When I run the script it gives the same answer(total words) for each text file, which is incorrect.

Professor Cowdawg just drew a red "X" across your assignment.

sub countWords { my $fname=join("/",@_); open FIN,"< $fname" or die "$fname:$!"; my @lines=<FIN>; chomp @lines; close FIN; my $count=0; foreach my $line(@lines){ map { $count++ } split (/[\s\t\n]+/,$line); } printf "There are %d words in %s\n",$count,$fname; }
You are not counting anything in your sub at all. You actually have to read the file in order to count the words in it.
