Crosstab Query that will count consecutively??????

[ind]

I have created a crosstab query that calculates to total purchases made from a supplier<br><br>Here's the SQL statement:<br><br>TRANSFORM Sum([Supplier Purchases].[PO Total]) AS [SumOfPO Total]<br>SELECT [Supplier Purchases].[Supplier Number]<br>FROM [Supplier Purchases]<br>GROUP BY [Supplier Purchases].[Supplier Number]<br>PIVOT Format([PO Date],&quot;mmm-yyyy&quot In (&quot;Jan-2000&quot;,&quot;Feb-2000&quot;,&quot;Mar-2000&quot;,&quot;Apr-2000&quot;,&quot;May-2000&quot;,&quot;Jun-2000&quot;,&quot;Jul-2000&quot;,&quot;Aug-2000&quot;,&quot;Sep-2000&quot;,&quot;Oct-2000&quot;,&quot;Nov-2000&quot;,&quot;Dec-2000&quot;<br><br>My question is, can the year (&quot;yyyy&quot automatically roll-over to 2001 on if the [PO Date] is in 2001??????<br><br>Thanks in advance
