Execute rowcount query and pass value as variable in a control flow

I know there is an abundance of information out there regarding what i am trying to do, and i have tried many of them with no luck.  I am sure it is something simple i am missing.  As usual, suggestions are gratefully welcomed !

I am using INTERSECT to find the duplicated between 2 tables.  I am obtaining the @@ROWCOUNT and assigning it to a column.  The query is such:

USE edgp
GO

SELECT @@RowCount as RCD1
FROM
(
 SELECT
   [txpid]
  ,[txpname]
  ,[txpadd1]
  ,[txpadd2]
  ,[txpcity]
  ,[txpst]
  ,[txpzip]
  ,[txphone]
  ,[txp_contac]
  ,[txpdba]
  ,[txp_begin]
  ,[phyadd1]
  ,[phyadd2]
  ,[phycity]
  ,[physt]
  ,[phyzip]
  ,[naic]
  ,[naic_desc]
  ,[Month]
 FROM edgp.DBO.EconDev_NewBusinessLicenses_Geocoded
 INTERSECT
 SELECT
   [txpid]
  ,[txpname]
  ,[txpadd1]
  ,[txpadd2]
  ,[txpcity]
  ,[txpst]
  ,[txpzip]
  ,[txphone]
  ,[txp_contac]
  ,[txpdba]
  ,[txp_begin]
  ,[phyadd1]
  ,[phyadd2]
  ,[phycity]
  ,[physt]
  ,[phyzip]
  ,[naic]
  ,[naic_desc]
  ,[Month]
 FROM edgp.DBO.EconDev_NewBusinessLicenses_2016
) D;

SELECT @@RowCount as [RCD]

The control flow is very simple, if duplicates exist, do not merge and exit.  If all values are unique, merge to the master data set.

I have set the execute SQL task general section as such:

Result set, i have created a variable User::RowCountDuplicate as int32 with value 0 (zero).  I have tried the value 0 and RCD as the Result Name, neither worked.

Based on the @@ROWCOUNT, i have set up constraint and expression:

When executing, this is the output I get:

SSIS package "C:\Users\oliver\documents\visual studio 2010\projects\NBL\NBL\Merge.dtsx" starting.
Error: 0x0 at Execute INTERSECT to detect duplicates before merging, want to avoid multi-merges of same dataset: No result rowset is associated with the execution of this query.
Error: 0xC002F309 at Execute INTERSECT to detect duplicates before merging, want to avoid multi-merges of same dataset, Execute SQL Task: An error occurred while assigning a value to variable "RowCountDuplicate": "Exception from HRESULT: 0xC0015005".

I think that covers it.  Again, I appreciate the help !
