I have a worksheet that keeps track of conference room reservations. I have 4 workbooks each with one quarter of the year for 2011. For the second quarter, on each worksheet for the workbook (see attached), I need to insert 17 Central 4 cells below 17 North on each sheet. So for instance, on the April sheet, 17 Central is on A 30, A 68, etc. I have entered 4 manually, but would need a macro to automate this process for the remainder of the April sheet and the other two months in this workbook, and in the workbooks containing the remaining two quarters of the year.
