The problem is in the indexi, it displays entreis like this: WHST.1.1: 11, 231, WB 1: 124, WB 1: 133, WB 2: 325, WB 2: 345, etc. In other words, it says WB 1 in front of every page number from the first workbook. Is there any way to consolidate the page numbers by book, e.g. output instead like this: WHST.1.1: 11, 231, WB1: 124, 133, WB 2: 325, 345 In other words, it list all page numbers for Workbook 1 right after WB 1: instead of placing WB 1 in front of every single page from Workbook 1? --Joel
