Hi there, and thanks for trying Qdabra's DBXL v2.3!
These are the steps you'll need to follow once you have designed your InfoPath form template:
1. Create a new document type.
2. Add SQL mapping.
3. Add SharePoint mapping.
4. Activate the form library to ensure forms open in the browser.
It sounds like you've already accomplished #2, which means you've also accomplished #1.
The details for Step #3 depend on your form and your environment(s). Are you using a form with code? Are SharePoint and DBXL on different machines? Maybe your form is simple and has no code.
