Summary method in PI ACE

Hi there,


I'm trying to use the Summary method in PI-ACE, but can't get the job done (I must say that I'm not the greatest programmer in the world )


This is my code, but I get an error message during debugging, so what going wrong?

Dim sdk As New PISDK.PISDK
Dim srv As Server
Dim ipiCalc As IPICalculation

Dim PI_point_Aktiv As PIPoint
Dim pdata_Aktiv As PIData
Dim ipid2_Aktiv As IPIData2
tagnameAktiv = TE_Name & ".Aktiv"

srv = sdk.Servers(PIServer)
ipiCalc = srv

PI_point_Aktiv = srv.PIPoints(tagnameAktiv)
pdata_Aktiv = PI_point_Aktiv.Data
ipid2_Aktiv = pdata_Aktiv

Dim AktivAverage As PIValue
AktivAverage = ipid2_Aktiv.Summary(dblStarttime, dblStarttime + 900, ArchiveSummaryTypeConstants.astAverage, CalculationBasisConstants.cbTimeWeighted)

 Debugging stops at the "AktivAverage = ipid2_Aktiv.Summary" part. The message is: Unable to interpret the variant type as a time.
