DECLARE @ValueTable TABLE ( Value VARCHAR (100) )

                    SELECT @sql = N'SELECT SRS_SizeSetDetails.'+@COLUMN_NAME+' FROM SRS_SizeSetDetails WHERE FSizeID = '''+@FSizeID+''' AND SRS_SizeSetID = '''+@SRS_SizeSetID+'''';

                    INSERT INTO @ValueTable
                    EXEC sp_executesql @sql;

                    SET @Value='';

                    SET @Value = (SELECT TOP 1  Value FROM @ValueTable)

                    DELETE FROM @ValueTable
