You should print out your @array to make sure it contains what you think it does: `use Data::Dumper; # ... # build @array # ... print Dumper( \@array );` [download]	[reply] [d/l]

Your `@array` variable is probably not properly populated and is likely to be empty (at least in part). This suggest that you might have an earlier problem reading the `testFile.txt` file. Perhaps you could change the file opening line as follows: `open FILE, "<", 'testFile.txt' or die "Cannot open testFile.txt $!";` [download] This will not solve the problem but at least it would tell you if the program failed to open the file. BTW, you should always check whether such OS related statements succeed.	[reply] [d/l] [select]
