“the_excerpt” in loop just keeps repeating first post?

the_post – Iterate the post index in The Loop. Retrieves the next post, sets up the post, sets the ‘in the loop’ property to true.

 while (have_posts())  { the_post();

after you trigger the_post your the_excerpt shold return different values.
