Using WinXP and Excel 2007 I need to setup a formula based on the date, (specifically the month) of the Monthly Report. If it is May through Sept. I need to use the Summer Rate from Summer Rate cell. If it is Oct through April then I must use the Winter rate cell in my calculation. I think this has to be an IF function but I don't know how to specify the month range to determine what rate cell to use to get the correct totals. I would really appreciate any help I could get
