It looks like you are storing the userCSRID value in a session variable and then trying to insert that session variable into your user_LogTime table. Do you get any record to insert into the table? Have you checked this session variable to ensure that it is has a value?
You can do a check just after the trigger for the insert by adding in this code:
// WA Application Builder Insert
if ($_SERVER["REQUEST_METHOD"] == "POST") // Trigger
{
die("the userCSRID is: " . $_SESSION['userCSRID']);
So long as this session variable has a value it should be inserted into the table. Also, I noticed the trigger for your login was login button pressed but the trigger for your insert is any page post. You should update the trigger for the insert to be like the trigger for your login.
