Pull The Posts Content

I have a database I built with Access with a Users_Table holding User_ID, User_Name, etc. A Posts_Table, with Post_Content, Post_ID, Post_DateandTime, Thread_ID (pointing to whichever thread the post is in from the Threads_Table), User_ID (pointing to the user who made the post in the Users_Table). Also a Threads_Table, with Thread_ID, and Thread_Title, etc.

I want to pull the Posts content, Post DateandTime, User who posted it, and thread title from the database (the page simply knows the ThreadID and the idea is to select all posts with that ThreadID). Could anyone help me create the SQL I need for this. I understand Inner Joins, and this would be the perfect place for them I would have thought, but I cannot get an inner join to work here. perhaps because this is an access created database,.
