Button to run AP Aging from Vendor

SOLVED

I created a button on the Vendor Maintenance screen that runs the AP Aging report.  I pass in the AP Division and Vendor numbers, but I can't get the report to filter by those values.  (Want to run the Aging for the Vendor displayed, like the Sage button does in Customer Maintenance.)

I suspect it is the "Tag$" syntax that is incorrect.  Here is my script:

strSelect = AP_Vendor_bus_APDivisionNo & AP_Vendor_bus_VendorNo
oARReport = oSession.GetObject("AP_AgedInvoiceReport_ui")
Set oARReport = oSession.AsObject(oARReport)

retval = oARReport.SelectReportSetting("STANDARD")
retval = oARReport.SetKeyValue("ReportSetting$","STANDARD")
retval = oARReport.SetKeyValue("RowKey$","1")
retval = oARReport.SetKey()
retVal = oARReport.SetValue("SelectField$", "Vendor Number")
retVal = oARReport.SetValue("SelectFieldValue$", "Vendor Number")
'retVal = oARReport.SetValue("Tag$", "TABLE=AP_Vendor;COLUMN=APDivisionNo$,VendorNo$;")   'incorrect syntax?
retVal = oARReport.SetValue("Tag$", "TABLE=AP_Vendor;COLUMN=APDivisionNo$;")     'tried setting it in 2 lines - no luck
retVal = oARReport.SetValue("Tag$", "TABLE=AP_Vendor;COLUMN=VendorNo$;")
retVal = oARReport.SetValue("Operand$", "=")
retVal = oARReport.SetValue("Value1$", strSelect)
retVal = oARReport.Write

retVal = oARReport.ProcessReport("PREVIEW")
retVal = oSession.DropObject("AP_AgedInvoiceReport_rpt")

Does anyone know what I'm doing wrong?  Thanks!
