What's wrong with my <cfoutput group>?

I don't recall ever having a problem with the <cfoutput> group attribute. But I can't figure out why it isn't woring right here. My table looks like this: ID       Date      ZIP code --------------------------------- 1       12/01/2008    27403 2       12/01/2008    90210 3       12/01/2008    45789 4       12/01/2008    27403 5       12/02/2008    55555 6       12/02/2008    21454 A simple query: <cfquery name="getshipcalclog" datasource="#APPLICATION.settings.dsn#"> SELECT estshiplogid, estshiplogdate, estshippostalcode FROM tblestshiplog ORDER BY estshiplogdate DESC </cfquery> Now, I just want to output the records grouped by the date. So there should be a date heading, and all the zip codes with records on  that date. <cfoutput query="getshipcalclog" group="estshiplogdate"> <h3>#estshiplogdate#</h3>   <cfoutput>   <p>#estshippostalcode#</p>   </cfoutput> </cfoutput> But it outputs every occurence of 12/01/2008 and its zip. When it should display 12/01/2008 as a heading, then fours zips below it. Then start another heading 12/02/2008, and two zips below that. What am I doin wrong here? Thanks! Will
