When using the Data Modelling function the Server Behaviors panel is greyed out

I am using Dreamweaver CS6 and I am trying to use the Data Modelling and Query Builder function following the online video.
I have created a test db with only 3 tables so its very simple, and I have a php page open in Dreamweaver.
I have created a database connection as described in the video and can see the tables OK in the databases panel.
I am also using a simple WAMP server setup on localhost.
I created the joins using the Data Model Interface and clicked OK and a webassist folder with an xml file is being created in my site folder.
However when I go to the Servers Behaviors panel the + sign is greyed out, so I cannot continue to create the joins.
Also just noticed my error messages are in French ................

I'd have to take a look to debug. Do you have a .php page open that is saved into your site with a testing server defined?

If so, please post a US phone number or Skype contact information and I'll look into this with you directly on Monday.

Hi Ray
I have used the testing server for other stuff so its working OK.
The database is connected OK (I clicked on test and it was successful) but the Server Behaviors panel is always greyed out, not like in the video tutorial.
However the Binding panel allows me to click + and choose MySQLi Recordset Query.
I have attached some screenshots which hopefully will help .......

The message that the query could not be inspected can be ignored. That is just because you are starting from blank. Dragging the tables and checking the columns you want to use will still create the proper select statement and should function properly.
