[support] drupal 7 menu problem

Hi, I am trying to create menus using on drupal 7.18 and they are not showing up. I'm not sure what I am doing wrong, been a wile since I did this. Did the following: Structure(Administer Menus Choose add menu and filled in the information Went to blocks and tried to place it in the side bar and saved. Now when I look at the main page no new menu. Also using this with Taxonomymenu I have this working on another site, but for the life of me I can not do it again and everything is setup the same unless I am forgetting to look some place. Thanks for any help.
