Why isn't this working?

Hey Everyone,
I am working on a database, and I want to set up a trigger. Here is the last outline of the two tables

Lighting:
|Index | col1 | col2 | Last Updated|
------------------------------------
|1     |info  |info. | 1618335050  |


Lighting Schedule:
|Index | time  | strength |
---------------------------
|1     |12:00  |0         |
---------------------------
|2     |13:00. |20        |
---------------------------
|3     |13:15. |25        |
---------------------------
|2     |13:40. |50        |

I have a python program that will delete all the rows in `Lighting Schedule` and replace insert new information. What I am looking for is a trigger that put a timestamp into row one column "Last Updated" in the `Lighting` table when that happens

The code below keeps shooting back a generic error.

Any ideas?


DELIMITER $$
CREATE TRIGGER 'LightingLastUpdated'
AFTER INSERT
ON `Lighting Schedule`
BEGIN
	UPDATE `Lighting` SET `Last Updated` = TIMESTAMP WHERE 'Index' = 1;
END$$

DELIMITER ;
