I did some experiments with table names and columns with spaces in them. The correct syntax for your database is INSERT INTO "Order List" ("Product ID", Quantity) VALUES ('example', 3). So, surround the table name with a double quotes ("), and the text value with a single quote (').
Aslo, the SQL Toolkit that you're using is pretty old and no longer supported by NI (for that matter, so is your version 6 of LabVIEW). The newer Database Connectivity Toolkit is easier to use. You don't have to know SQL to use it in a lot of cases.
