I am not sure if this is possible, but I have a Page Numbers field that could contain various numbers. I basically want to assign a number to each page number in increments of 5. The count of 5 would need to start from the first page number, no matter what it is The problem is that my data doesn't contain all page numbers in sequential order and page numbers could be duplicated. I also have different years and would want the 5 count to start over based on the year. I've attached two examples. This would be a lifesaver! Thanks!
