I was wondering if someone could point me in the right direction. I have this code. They idea I had behind it is to insert values into different tables depending on variables being passed. 

So when user fills out a form and selects $stream="nursing" I want results to go to table 'users' and 'Family1', but not 'Family2' table. and if user selects $stream='doctoral' results should go to table 'users' and  'Family2', and not go to 'Family1'

But with my query I get results go to both table and also users table. And there is no restriction to what users selects, variable $stream being passed no matter what it is.

Is this the wrong way to go here? Did I completely mess up the logic?
