Queries :: Find Unmatched Query - Design View

I need constructing a find unmatched query. I don't really know what I'm doing with SQL and I think that I can only take things so far with query design view.

I have two tables. T_Productions and ProPro (see attached). In Access query design, I can only specify one matching criteria. I need a query that will show me records from T_Productions that don't have matching Production_Code (PpNum in ProPro), Avantage_Product_Code (PpPrNum in ProPro) and Step (PpEtape in ProPro) in ProPro.

What I have now only gives me the records where Avantage_Product_Code don't match PpPrNum.

Code:
SELECT T_Productions.ID, T_Productions.Production_Code, T_Productions.Avantage_Product_Code, T_Productions.Step, T_Productions.Quantity_Required
FROM T_Productions LEFT JOIN ProPro ON T_Productions.[Avantage_Product_Code] = ProPro.[PpPrNum]
WHERE (((ProPro.PpPrNum) Is Null));
