That'll teach me to do this stuff without a smoke break all afternoon. Just realized there's an even easier way to do this. Instead of all that logic in the union query, we can get the same results mathematically. Here's the new Union Query: SELECT ALL W As Field, IIF(Not IsNull([W]),1,null) AS FieldHasData, ID FROM tblWilliam UNION ALL SELECT X As Field, IIF(Not IsNull([X]),2,null) AS FieldHasData, ID FROM tblWilliam UNION ALL SELECT Y As Field, IIF(Not IsNull([Y]),3,null) AS FieldHasData, ID FROM tblWilliam UNION ALL SELECT Z As Field, IIF(Not IsNull([Z]),4,null) AS FieldHasData, ID FROM tblWilliam; Note that all the goofy logic is gone. Instead, if that field is not null, it gets a value equal to it's position (1 through 4, equating to W,X,Y,and Z). If it doesn't have a value, then FieldHasData is Null. With that in mind, instead of summing that field, we make the Series field be the Max-Min of FieldHasData + 1. Here's the new totals query: SELECT tblWilliam.ID, Max([FieldHasData])-Min([FieldHasData])+1 AS Series, tblWilliam.W, tblWilliam.X, tblWilliam.Y, tblWilliam.Z, Max(qryUnionedFields.Field) AS MaxOfField FROM tblWilliam INNER JOIN qryUnionedFields ON tblWilliam.ID = qryUnionedFields.ID GROUP BY tblWilliam.ID, tblWilliam.W, tblWilliam.X, tblWilliam.Y, tblWilliam.Z ORDER BY tblWilliam.ID; That way, if you need to add or remove fields, all you have to do is add another line to the union query (and add the field to the totals query), and the only 'check' would be to make sure that the 'true' part of the IIF statement is sequenced (1, 2, 3,...etc). Next time you have a problem like this, start with 'Drew, I'm trying too..... now, go smoke, and tell me how to do that.
