Insert instead of from select and inserted data - sql

Question

I'm having trouble creating a trigger in a SQLite DB on a view that inserts values into 2 different tables and then inserts the "ID" values from those tables and values from the inserted data into a 3rd table. So basic idea is ....
CREATE TABLE [TBL1] (ID UNIQUE INT AUTOINCREMENT,VAL1);
CREATE TABLE [TBL2] (ID UNIQUE INT AUTOINCREMENT,VAL2);
CREATE TABLE [TBL3] (ID1 INT,ID2 INT,VAL3);
CREATE VIEW [v_TBL3] AS
SELECT (TBL1.VAL1,TBL2.VAL2,TBL3.VAL3)
FROM TBL3
INNER JOIN TBL1 ON TBL3.ID1 = TBL1.ID
INNER JOIN TBL2 ON TBL3.ID2 = TBL2.ID;
========== heres the problem ==========
CREATE TRIGGER [t_TBL3_INSERT] INSTEAD OF INSERT ON v_TBL3
BEGIN
INSERT OR IGNORE INTO [TBL1] (VAL1) VALUES NEW.VAL1;
INSERT OR IGNORE INTO [TBL2] (VAL2) VALUES NEW.VAL2;
INSERT INTO [TBL3] (ID1,ID2,v_TBL3.VAL3)
SELECT (TBL1.ID,TBL2.ID,VAL3)
FROM TBL1,TBL2,v_TBL3
WHERE TBL1.VAL1 = v_TBL3.VAL1 AND TBL2.VAL2 = v_TBL3.VAL2;
END;
I've looked on around on the net but I'm not finding quite what I need to get me there. Can someone help me get there?

You did not mention what your problem is, but when using proper SQL syntax, your schema would look like this:
CREATE TABLE TBL1 (ID INTEGER PRIMARY KEY AUTOINCREMENT, VAL1);
CREATE TABLE TBL2 (ID INTEGER PRIMARY KEY AUTOINCREMENT, VAL2);
CREATE TABLE TBL3 (ID1 INT, ID2 INT, VAL3);
CREATE VIEW v_TBL3 AS
SELECT TBL1.VAL1, TBL2.VAL2, TBL3.VAL3
FROM TBL3
INNER JOIN TBL1 ON TBL3.ID1 = TBL1.ID
INNER JOIN TBL2 ON TBL3.ID2 = TBL2.ID;
CREATE TRIGGER t_TBL3_INSERT
INSTEAD OF INSERT ON v_TBL3
BEGIN
INSERT OR IGNORE INTO TBL1 (VAL1) VALUES (NEW.VAL1);
INSERT OR IGNORE INTO TBL2 (VAL2) VALUES (NEW.VAL2);
INSERT INTO TBL3 (ID1, ID2, VAL3)
SELECT TBL1.ID, TBL2.ID, VAL3
FROM TBL1, TBL2, v_TBL3
WHERE TBL1.VAL1 = v_TBL3.VAL1 AND TBL2.VAL2 = v_TBL3.VAL2;
END;
