Mysql: execute command denied to user ''@'localhost' for routine error

It works.....I try to grant this priviledge in root.

log in as root
GRANT EXECUTE ON PROCEDURE TestMediaControl.monthavrage TO 'jeinqa'@'localhost'
flush privileges;

Very late to the party also try a combination of.

GRANT EXECUTE ON PROCEDURE TestMediaControl.monthavrage TO 'jeinqa'@'%';

AND

flush privileges;

Also try replacing PROCEDURE with FUNCTION.

mysql mysql-error-1064 privileges grant

I have encountered this in phpMyAdmin, a few hours ago, when executing a stored procedure with what I thought would be detected as a syntax error.

I was missing a comma between a field name, and a calculated field, and this gave me the same error message.
