TRANSFORM query for MS Access using .NET

Below I can't do the first query but can do the second query. The queries are the same, creating a make table query on the result of another query, but the second query has a TRANSFORM and PIVOT part while the first doesn't. So, I don't know much abou that type of query... except that it didn't work... what's the reason for that? (I mean, both simply produce a table as a result... so I don't know why I can't call that table 'Temp' and then SELECT INTO a new table called RevenueByCountryAct.

CAN'T do this query

strSQL = "SELECT Temp.* INTO RevenueByCountryAct FROM"
strSQL = strSQL + " (TRANSFORM Sum([Table1].BillAmount) AS SumOfBillAmount"
strSQL = strSQL + " SELECT [Table1].FILESOURCE, [Table1].TYPE, [Table1].[Product Code], [Table1].Service, [Table1].Service2, [Table1].Service3, [Table1].COUNTRY"
strSQL = strSQL + " FROM [Table1]"
strSQL = strSQL + " GROUP BY [Table1].FILESOURCE, [Table1].TYPE, [Table1].[Product Code], [Table1].Service, [Table1].Service2, [Table1].Service3, [Table1].COUNTRY"
strSQL = strSQL + " PIVOT [Table1].[Billing Period]) AS Temp"

Select allOpen in new window

CAN do this query

strSQL = "SELECT Temp.* INTO RevenueByCountryAct FROM"
strSQL = strSQL + " (SELECT [Table1].FILESOURCE, [Table1].TYPE, [Table1].[Product Code], [Table1].Service, [Table1].Service2, [Table1].Service3, [Table1].COUNTRY"
strSQL = strSQL + " FROM [Table1]"
strSQL = strSQL + " GROUP BY [Table1].FILESOURCE, [Table1].TYPE, [Table1].[Product Code], [Table1].Service, [Table1].Service2, [Table1].Service3, [Table1].COUNTRY"
strSQL = strSQL + ") AS Temp"
