User Defined Data Type

I am trying to consume a webservice which requires that I pass 3 values as a single parameter. I have created a module in Access 2007 with the following code.
---------------------------------------------------------------------------------------------------------------------------
Option Compare Database
Option Explicit

Public Type UserIDBean
    UserName As String
    Password As String
    Version As String
End Type
--------------------------------------------------------------------------------------------------------------------------

Public Function TimesheetData(BeginningDate As Date, EndingDate As Date) As Variant
On Error GoTo HandleError

    Dim AdminIDBean As UserIDBean
    Dim objSoapClient As SoapClient30
    Dim varItems As Variant
   
    Set objSoapClient = New SoapClient30
   
    Call objSoapClient.MSSoapInit(par_WSDLFile:="https://timecardweb.econz.com/axis/services/timecard1Soap?wsdl")
    Call objSoapClient.EServiceTimecardSoapInterface.UserIDBean

    AdminIDBean.UserName = "webuser"
    AdminIDBean.Password = "webpassword"
    AdminIDBean.Version = objSoapClient.NADSWebserviceVersion.TIMECARD_VERSION_1

    TimesheetData = Array(objSoapClient.getDetailedHourSummaries(AdminIDBean, BeginningDate, EndingDate, "UTC-6"))

ExitHere:
    Exit Function

HandleError:
    MsgBox "The TimesheetData Function encountered an unexpected error. " & Chr(13) + Chr(10) & _
        "The Error Number is: " & Err.Number & Chr(13) + Chr(10) & _
        "The Error Description is: " & Err.Description, vbExclamation, "Error Handling Routine"
    Resume ExitHere

End Function
-------------------------------------------------------------------------------------------------------------------------------

Compile Error:

Only user-defined types defined in public object modules can be coerced to or from a variant or passed to late-bound functions.

The AdminIDBean is highlighted.

Thanks for the help.
