Dynamic Daily totals

I have a workbook that tracks daily totals from 6 different time period throughout the day. I created a new page for totals. I used COUNTIF functions to count words for a given time period. Each day a new set of 6 columns are added for that given day. I need the totals to be locked to the given time periods. When ever new columns are added they shift down the sheet. Even attaching absolute cell references wont work. PLEASE HELP!
