You have to dynamically build the SessionID into the future requests after the request that gives you the session ID.
The easiest way to perform this is to do a property transfer and store it to a property (IE, SessionID) and then use ${#TestCase#SessionID} to put the session ID where it belongs. Or you can build a different transfer for each request. I personally prefer the first method.
The other option is a groovy script that dynamically builds and adds the data into the requests. This is more difficult and better suited if your setting it up to dynamically build several parameters within your requests.
