Insert into statement

I am trying to Insert values into a table using the following query and I get Query completed with errors and I don't know what is causing it.

Declare @gSource int;
Declare @bSource int;

Set @gSource = 143692;
Set @bSource = 138450;

/*SELECT ProjectID, BinderSection,BinderTab
FROM hcc_tblProjects2Sources
WHERE SourceID = @bSource
EXCEPT
SELECT ProjectID, BinderSection,BinderTab
FROM hcc_tblProjects2Sources
WHERE SourceID = @gSource;
*/

INSERT INTO hcc_tblProjects2Sources(ProjectID, BinderSection, BinderTab, SourceID)
VALUES(
	(SELECT ProjectID, BinderSection,BinderTab
	FROM hcc_tblProjects2Sources
	WHERE SourceID = @bSource
	EXCEPT
	SELECT ProjectID, BinderSection,BinderTab
	FROM hcc_tblProjects2Sources
	WHERE SourceID = @gSource)
	,@gSource
);

Select allOpen in new window

The part commented out returns 6 rows. I want to put those rows into a table and then a hard coded value of @gSource for all of them.
