SC9 features on your website for Master/Detail not working

Hello SC

I went here: Master/Detail
"In this example a complete master / detail application is developed. Here two forms are created. The first (Master) is based on the orders table and the second (Detail) is based on the orders details. "

http://www.scriptcase.net/scriptcase-samples/php-form/master-detail/

I tried to add a new order detail.

  1. Doesn’t let you enter a quantity.
  2. Save gives error: [INDENT]Error inserting:
    near “,”: syntax error[/INDENT]

If someone from SC sees this message, would you please reply. (Otherwise I guess there is no point in alerting you to these issues).
