what I'm hoping to accomplish is to dynamically create columns as needed within a stored procedure. My issues lies in the fact that a drive may no incentives, 1 incentive or multiple (2,3,4.etc) incentives assigned to the drive. Screen shot below for example data:

I initially used the FOR XML Path to concatenate records:

Stuff ((Select ', ' + isnull(EM.Description,'')
    From EquipmentMaster EM
        Inner Join EquipmentDetail ED On EM.EquipmentID = ED.EquipmentID And EM.EquipmentType=3
        Where ED.DriveID = DM.DriveID
            For XML PATH(''), TYPE).value('.', 'varchar(max)')
            ,1, 2, '') as [Incentives]

But the end users have requested the incentives be in separate columns. I am trying to reuse some code I found here: Stack Overflow link

But I cannot get it to work. Was hoping to get some help to make this procedure work.

Here is the procedure code:

declare
@startDate datetime,
@endDate datetime,
@RegID varchar(8000),
@OrgID varchar(8000),
@SubID varchar(8000),
@COID varchar(8000),
@RecID varchar(8000),
@StatusID varchar(8000),
@Cols nvarchar(max),
@Incentives nvarchar(max)

Select @Cols = Stuff ((Select ', ' + isnull(EM.Description,'')
            From EquipmentMaster EM
            Inner Join EquipmentDetail ED On EM.EquipmentID = ED.EquipmentID And EM.EquipmentType=3
            --Where ED.DriveID = DM.DriveID
            For XML PATH(''), TYPE).value('.', 'varchar(max)')
            ,1, 2, '')

Select
DM.DriveID [DriveID],
DM.FromDateTime [FromDateTime],
Case When DM.OwnerType = 0 Then Acct.Name Else CD.DescLong End As [OwnerName],

Stuff ((Select ', ' + isnull(EM.Description,'')
    From EquipmentMaster EM
        Inner Join EquipmentDetail ED On EM.EquipmentID = ED.EquipmentID And EM.EquipmentType=3
        Where ED.DriveID = DM.DriveID
            For XML PATH(''), TYPE).value('.', 'varchar(max)')
            ,1, 2, '') as [Incentives]
From
rpt_DriveMaster DM
Left Outer Join rpt_Accounts Acct on DM.AccountID=Acct.AccountID
Left Outer Join IDViewRecruiters Rec on Acct.RecruiterID=Rec.CodeID
Inner Join rpt_CenterDetail CD on DM.CenterID=CD.CenterID

Where
DM.StatusID <>5
And DM.FromDateTime Between '03/01/2015' AND '03/02/2015'

Here is my original procedure that works to bring all incentives into one column (and used by SSRS to display a report):

Create Procedure Hema_IncentiveReport
@startDate datetime,
@endDate datetime,
@RegID varchar(8000),
@OrgID varchar(8000),
@SubID varchar(8000),
@COID varchar(8000),
@RecID varchar(8000),
@StatusID varchar(8000)
