you should set the inner (in @SQL) '@CheckQuantity' as OUTPUT. try this:

SQL

DECLARE @CheckQuantity INT
declare @ParmDefinition nvarchar(100)
declare @SQL nvarchar(100)

SET @ParmDefinition = N'@CheckQuantity INT OUTPUT'
SET @SQL = N'SET @CheckQuantity= 12'
PRINT @SQL

EXEC [dbo].sp_executesql @SQL, @ParmDefinition,@CheckQuantity=@CheckQuantity OUTPUT;
PRINT @CheckQuantity
