PHP - Nested Pdo Queries Stopping After 1st Run

I'm writing PHP for my son's cub scout pack.  It populates the MySQL db users table from data contained in a csv file. 
So far, it puts the scout's info in just fine...until I try to run another query as a nested query to retrieve the auto-generated userID for the scout that was just placed in the DB.

The result of this if I don't include the second query--the one trying to get the new userID for that scout, it iterates through the whole file as expected and puts all the scouts in the users table.  The second I uncomment the 2nd query and try to get it to run, it only puts the 1st scout in the DB, properly retrieves the newly generated userID for him, and then stops. 

I need to have this userID for the scout to properly associate that scout with the parents later on and in other sections of this project. 

the db_connect() function just creates the PDO object and contains the username, etc for the connection.  That part is working fine so I'm not posting that function here.

I've tried renaming the connection, query, etc to add "ID" to the end to ensure I wasn't trampling on var names, but that hasn't made a difference


Code: [Select]
//include necessary files:
 include_once("../../sys/php/includes/data_fns.php");
 
 //start session
 session_start();
$conn = db_connect();
$bufferConn = $conn->setAttribute(PDO::MYSQL_ATTR_USE_BUFFERED_QUERY, true);
