I have a report where I have to use my footer summary information in place of some difficult-to-trap append fields. If what you have is truly append-type information, but simply placed below your detail fields, try changing the template type from "append" to "footer" and see if everything becomes consistent with your report structure.
If you had the case where each detail line had a different (lower) append field, you could trap your current append fields as your detail fields, and work upwards from there. This is probably not the case with your report.
Try changing the "append" to "footer" trick. If that doesn't work, feel free to contact me directly (e-mail or private message).
