Unknown column 'a.id_employee' in 'on clause'

[blake5995]

I turned error reporting on and I am getting this. I have been trying to track down why the "contact us" isnt working aswell as proceeding to checkout in the shopping cart. Thanks

 

		SELECT SQL_CALC_FOUND_ROWS
		 a.*
		, CONCAT(LEFT(e.firstname, 1), '. ', e.lastname) employee
		FROM `ps_log` a
		
		 LEFT JOIN ps_employee e ON (a.id_employee = e.id_employee) 
		
		WHERE 1 
		
		
		ORDER BY a.`id_log` ASC LIMIT 0,50
