PHP - Help with Edit Page

I am trying to finish work on an edit page and having a problem with the UPDATE statement.

I am trying to make a page for user to edit their information and I have set up a hash encrytped password field that users can reset on their password page. I have made an if statemetent that will update the password cell in the DB if it is filled in or leave the password un touched if it is empty.

I think I have my statement almost correct but although I am getting a successful entry to the DB message nothing is being entered, can anyone help?

(PS. this edit statement is from a page that lists/add/edit and delete the DB info)
