I have this SQL SELECT e1.*, l1.* FROM e1 INNER JOIN l1 WHERE e1.entre_active = 'Y' AND l1.entreID = e1.entre_id The above query works but i want to add the one below SELECT SUM(a1.adp_amount) as amount FROM a1 WHERE a1.adp_loanID = e1.loanID; the last part of the query is to SUM the part payment made on table 'l1' and return total raised with the first query. the whole idea is three tables, (business, loan, raised), loan referenced ID from business, raised referenced ID from loan. loan maybe $300 and it can be raised over time till completed, so all the amount raised + the loanId will be stored inside the raised table. Thank you
