Session Issue

[mcmuney]

I'm using the code below to display new members to my site.
PROBLEM: It works, but ONLY when I'm logged in. When I logout, it displayes blanks. I don't have and sessions code on here. I tried adding it, it still doesn't work.
QUESTION: What am I missing?

[code]
  <?

$days_val=1;

$sec=$days_val*86400;



$curr_time=time();

$maxtime=$curr_time-$sec;



$sql = "select s1.* from sc_member s1,sc_member_images s2 where s1.scm_mem_id!=$social_mem_id and s1.scm_mem_id=s2.scm_mem_id and s2.sci_main=1 and s1.scm_regdate>$maxtime order by rand() limit 0,2";

$new_mem = $db->select_data($sql);

for ($i=0 ;$i< count($new_mem);$i++ )

{

?>

<?

$imgpath=$db->show_mem_image($new_mem[$i]['scm_mem_id'],$new_mem[0]['scm_gender'],1);

?>
  <a href="social_mem_profile.php?scm_mem_id=<?=$new_mem[$i][scm_mem_id]?>" class=border>

<img src="gd.php?pic=<?=$imgpath?>&w=100&h=75&enlarge=yes" width=100 height=75 border=1 class=border></a>

              <?

  }//for

  ?>
[/code]

I think I solved it, I removed "s1.scm_mem_id!=$social_mem_id and" from the code.
