Hi,
It appears that you are asking two questions here.
Regarding your first question on how to configure one of your phone numbers using a .vxml file stored in your file repository, here are the instructions:
1) Log into your hosting account at
http://hosting.plumgroup.com.
2) Go to Application->Application Configuration.
3) Click on "Edit" for one of your phone numbers.
4) For Application Source, click on the drop-down menu and select "Repository File".
5) For Repository File, click on the drop-down menu and select the .vxml file that you wish to use.
6) Click on "Save" to save the application configuration for your phone number.
From there, you should be able to dial into your phone number to use .vxml file from your file repository.
Regarding your second question on getting an order number from a user and POSTing it to your application server to be fetched, you can use either the <submit>, <subdialog>, or <data> tag. For more information on how to use these VoiceXML tags, please see our documentation here:
