Error 1064 - You have an error in your SQL syntax;

I am new to developing field, and I have encountered an error while creating a trigger.Could anyone please figure out what is the error?

DELIMITER $

CREATE TRIGGER update_feedback_dashboard
AFTER INSERT
ON tblcustomfeedback FOR EACH ROW

BEGIN

DECLARE averageScore float default 0;
DECLARE avgscore float default 0;
DECLARE IdCount float default 0;

SELECT SUM(avg_score) into avgscore, COUNT(Id) into count FROM tblcustomfeedback  WHERE feedbackDate = NOW() ORDER BY Id DESC LIMIT 1;

SET averageScore  =avgscore;
SET IdCount  =  count;

IF (SELECT count(*) FROM tblfeedbackdashbd WHERE Date=CURDATE()) = 0 
THEN
 INSERT INTO tblfeedbackdashbd(AverageScoresAday ,Date)     VALUES(averageScore/IdCount,CURDATE());
ELSE   
 UPDATE tblfeedbackdashbd SET AverageScoresAday=averageScore/IdCount  WHERE   Date=CURDATE();
END IF;
END $

The error encountered is,


[Err] 1064 - You have an error in your SQL syntax; check the manual
that corresponds to your MySQL server version for the right syntax to
use near 'COUNT(Id) into count FROM tblcustomfeedback WHERE
feedbackDate = NOW() ORDER BY' at line 11

The syntax is not:

SELECT id INTO @x, data INTO @y ...

but it is:

SELECT id, data INTO @x, @y ...

Use:

SELECT SUM(avg_score), COUNT(Id)
  INTO averageScore, IdCount
FROM ... ;
