How to retrieve returned values from and MS Access Passthru Query , executing a SQL stored procedure

I am a NUB working with a SQL Server back end from withing MS Access 2013.  With help from EE I was able to create some code to invoke a stored procedure and even pass some values from a pass thru query.

With DBEngine(0)(0).CreateQueryDef("")
         .Connect = gConnection
         .ReturnsRecords = False
         .SQL = "EXEC dbo.sptblEventsAdd"
         .SQL = .SQL & "  @EventID    = " & long1
         .SQL = .SQL & ", @PropertyID = " & long2
         .Execute dbSQLPassThrough + dbFailOnError
End With

This worked well ad that SP does not return any values.  When I tried to modify the code to execute an SP that returns one value it didn't work.  The SP would execute but I wasn't picking up the returned value.  My final iteration of code does not execute but give me a message "Cannot execute Select Query".

This is my final iteration of code:
With DBEngine(0)(0).CreateQueryDef("")
         .Connect = gConnection
         .ReturnsRecords = True
         .SQL = "EXEC dbo.spGetNextReceiptNum"
         .SQL = .SQL & "  @MuniCode         = " & muni
         .SQL = .SQL & ", @NewReceiptNumber = " & returnNextReceipt    ' this is returned field
         .Execute dbSQLPassThrough + dbFailOnError
End With

This is the SPROC I want to execute.  It return one int value

USE [JTSConversion]
GO
/****** Object:  StoredProcedure [dbo].[spGetNextReceiptNum]    Script Date: 4/21/2017 11:01:57 AM ******/

ALTER PROCEDURE [dbo].[spGetNextReceiptNum]
      -- Add the parameters for the stored procedure here
      @MuniCode           int = 0,
      @NewReceiptNumber   int = 0    Output
AS
BEGIN
      -- SET NOCOUNT ON added to prevent extra result sets from
      -- interfering with SELECT statements.
      SET NOCOUNT ON;

      Declare @WkReceiptNum      int   = 0,
              @NextReceipt_C  Int   = 0

 -- Retrieve NextReceipt_C

        SELECT
           @NextReceipt_C = NextReceipt_C
        FROM
           tblMuni_Master
        Where
           MuniCode = @MuniCode

    -- Add 1 to the Receipt Number

       SET @NextReceipt_C = @NextReceipt_C + 1
       SET @NewReceiptNumber = @NextReceipt_C

   -- Update the Table

        UPDATE
           tblMuni_Master
        SET
           [NextReceipt_C] = @NextReceipt_C
        WHERE
           [MuniCode] = @MuniCode


END

Does anyone know what my code would have to look like to pass one value and return one value, without getting an error message?
