view my profile & edit profile

-- url of the page with the problem -- : www.dealsplate.com
when a registered customer is trying to check his/her profile...the data is being fetched from jos_users table . I want the data to be fetched from hikashop's jos_hikashop_address and joe_hikashop_user tables and displayed.

Also edit profile is writing to jos_user table not the hikashop tables.

I am very very new to website designing php and XML. Kindly explain in detail.

where can i find the query that is fetching the data for view my profile form so that i can change the source tables in it.

I am having this problem because the hikashop registration form is not synching the new data into joomla's user table and all the fields are empty beside name, username and email_id.
