1) Do you need exact 5 months for DueRO? It is fine for 5/2/08. But if it is 1/31/08? Adding 5 months will give 6/31/08?? Similar situation for February.

2) This is Excel function (Date). DateAdd or DateDiff are not in Excel 2007. But you may write similar code in Access using VB code. Or as Mshen suggested you can test in Excel & then use Access to link the excel worksheet.

3) The trick to get the last day of a month is to define the 1st day of next month & then subtract 1 day. Excel (and VB) will automatically adjust the date.

Please keep us posted with your approach. Good luck.
