How can I do this correctly?
INSERT INTO tbl_task (`Assignedby`,`userID`)
SELECT ID FROM tbl_users WHERE UserName='$_GET[u]',
SELECT ID FROM tbl_users WHERE UserName='$_GET[at]'

Assuming you want to insert one row with two columns, I think you might want this:
INSERT INTO tbl_task(`Assignedby`, `userID`)
SELECT (SELECT ID FROM tbl_users WHERE UserName='$_GET[u]'),
(SELECT ID FROM tbl_users WHERE UserName='$_GET[at]');

As the title suggests, trying to take the count or possibly distinct count of a column, we call it year, to count the number of a years for an individual or populated ID and place it another column in the same table. Here is an idea of what I have so far and we want to update the table. Thank you.
Join group table to updated table directly:
UPDATE outputtable O JOIN
(SELECT personID, COUNT(DISTINCT year) AS countYear
FROM outputtable GROUP BY personID) temp ON O.personID=temp.personID
SET O.N=temp.countYear

CREATE TRIGGER NOTICE_ISSUE
AFTER INSERT ON MEMBERS
FOR EACH ROW
INSERT INTO NOTICE (Ssn,LSSN,NOTICE_TYPE) VALUES
((SELECT Ssn from MEMBERS WHERE CURDATE() = NOTICE_DATE),
(SELECT LIB_SSN from MEMBERS WHERE CURDATE() = NOTICE_DATE),'RENEW YOUR MEMBERSHIP');
You are duplicating the select query, it would be better like this:
CREATE TRIGGER NOTICE_ISSUE AFTER INSERT
ON MEMBERS
FOR EACH ROW
INSERT INTO NOTICE (Ssn,LSSN,NOTICE_TYPE)
SELECT Ssn, LIB_SSN, 'RENEW YOUR MEMBERSHIP'
FROM MEMBERS
WHERE CURDATE() = NOTICE_DATE
