labyrinth248:What I would like to do is save the form in .html format once form is completed
You did not provide any concrete details, And there are quite a plethora of books and online tutorials for introduction to Sharepoint and Infopath architecture/paradigm/philosophy.
Infopath forms are XML based and basically just provide XML data for their use (rendering of forms and XML data in them) by other tools, frameworks, services, packages, etc.
Also and mainly they are used EXTERNALLY (by external "tools").
And Infopath Designer is not web development tool (or HTML editor, creating/changing/updating/mapping HTML), it is XML (forms) editor for creating forms to be used in many possible formats, in many contexts externally.
For example, HTML (webpage) is generated by Infopath Form Service which is the enterprise feature of Sharepoint Server 2010 from Infopath XML data form and linked to it Infopath XSN form template.
The latter is stored, registered and used on Sharepoint Server site as precompiled Infopath Web Part (object).
If you are not going to reverse engineer and hack Sharepoint Server, then you should use the same tools and functionalities provided by them through which you generate(d) "HTML" webpage and/or from their context (External to Infopath form editing/creation).
There you most probably will see a violet icon of (compiled) Infopath Form Web Part (generated from published IP template) with contextual options "Edit Web Part" and "Add a Web Part" link.
Through the latter you can embed built-in and previously deployed/published to Sharepoint Server site web parts (incl. Infopath Form Web Parts).
Upon adding another web part, you should see contextual choice Connections with subchoices depending on how and what you use with, for example:
- Send Table To
- Send Row of Sata To
- Get Parameters From
- Get Filter Values From
You should look into how to use what is provided by a "platform" first instead of trying to subvert (substitute, overrrun or overcomplicate) what is provided OOTB
