Issues with Session Variable on page

I have a login page where i need to set the session variable ‘realtor_ID’ to the Query id that is displayed on the page.

For instance, the page is using the ?realtor_ID=4

so i need to get that and assign the Session realtor_ID = 4

I have setup Global Session for realtor_id
I have setup a Set Session Value to get the value and set it
I have setup Session Storage manager and applied the realtor_ID
I have also setup the ServerConnect to the database function where the realtor_ID is being set.
However i cannot get the realtor_ID session to set and display

Any reason why?
