PHP - Inserting Multiple Values Into Mysql

Hi,

My company has 240+ locations and as such some users (general managers) cover multiple sites.  When I run a query to pull user information, when the user has multiple sites to his or her name, its adds the second / third sites to the next columns, rather than wrapping it inside the same table cell.  It also works the opposite way, if a piece of data is missing in the database and is blank, its pull the following columns in.  Both cases mess up the table and formatting.  I'm extremely new to any kind of programming and maybe this isn't the forum for this question but figured I'd give it a chance since I'm stuck.

The HTML/PHP code is below:

<table id="datatables-column-search-select-inputs" class="table table-striped" style="width:100%">

                                        <thead>

                                            <tr>

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?
