This is a followup to tilly's post, above. One place to look in this subroutine -- which is using globals -- is at your variables. The output suggests that the value set in a previous call to the sub is being re-used in subsequent calls. If you use my to declare those variables in the subroutine, this can't happen, and moreover, if anything goes wrong and you inadvertently assign undef to one of them, you'll get a warning (provided you turn on -w or use warnings. This will help you track down errors.
