InfoPath Dev

I made a form form a Sample form in InfoPath, but it won't let me get rid of the sample form data Source. When I try to pick a data Source from the SQL Data base that I created, it's not there. Please help...

Is it a primary data connection or secondary data connection?

If it is a primary data connection , then use the option "convert main data source" in tools menu.

If it is a secondary data connection, go to "tools-->data connections" and remove the existing data connection and add the new data connection which ever you want.

It's a main data source, but when I went to tools and convert data source it is asking me to Browse for or "Enter the location of the XML document or schema that you want to use as your data source"
Please help...this may be simple solution though
