Undefined variable in Form

[apparelbusiness.com]

I have an application (that has been around for 2 years) that when the we click on Create Order button it us supposed to display 2 form widgets, order header and order detail. But when it we click on the button the screen just hangs and nothing happens so then I checked the error log

The error log is showing the below error messages.

So then I checked the widget and the widget is showing those fields as Undefined on the form ?
