question

i work on sql server 2012
i get error as below:
The select list for the INSERT statement contains fewer items than the insert list. The number of SELECT values must match the number of INSERT columns.

statement generate error

   INSERT INTO [ExtractReports].dbo.AllData(PartID,Code,CodeTypeID,RevisionID,ZPLID,FeatureName,FeatureValue,ConCount) SELECT  PartID,Code,Co.CodeTypeID,Co.RevisionID,Co.ZPLID, STUFF((SELECT  + CAST(d.ColumnName AS VARCHAR(300)) AS [text()]
                  FROM [ExtractReports].dbo.PartAttributes t1 with(nolock)
                   inner join core_datadefinitiondetails d with(nolock) on t1.ZfeatureKey=d.columnnumber
                WHERE t1.PartId = PM.PartId 
                FOR XML PATH(')), 1, 1, NULL) AS Featurekey,
              STUFF((SELECT  + CAST(O.Name AS VARCHAR(300)) AS [text()]
                FROM [ExtractReports].dbo.PartAttributes  AS O
                WHERE O.PartId = PM.PartId 
                FOR XML PATH(')), 1, 1, NULL) AS FeatureValue,Count(1) as ConCount
                     FROM 
                     [ExtractReports].dbo.PartAttributes PM 
                     INNER JOIN    [ExtractReports].dbo.Condition Co ON Co.ZfeatureKey = PM.ZfeatureKey Where (1=1 and   (PM.ZfeatureKey= 1501170111 And Name ='Zener') ) Group By PartID,Code,Co.CodeTypeID,Co.RevisionID,Co.ZPLID  Having Count(1)>= 1

so why this statement generate that error
