How do I set variables?

[Sketch]

LOL....

This SUCKS!

Okay, This is what is in my showthread.php at the very end of the file:

PHP Code:

//*********************Custom Field Hack********************
$tid = $thread[postuserid];
$customsql=mysql_query("SELECT * FROM userfield WHERE userid = '$tid'") or die(mysql_error());

while($custom=mysql_fetch_array($customsql)){

$field7 = $custom['field7'];

if($field7 == NULL)
{
$cdnow = "";
}
else
{
$cdnow = "<b>CD I am Playing:</b> <br>$field7";
}

eval("\$cdnow = \"".gettemplate('postbit')."\";");
}
//**********************************************************
eval("dooutput(\"".gettemplate("showthread")."\");");
?> 


And my postbit portion:

PHP Code:

<b>$post[avatar]</b> 
<normalfont><br>
   <b>$post[username]</b>
</normalfont><br>
<smallfont>
   $post[usertitle]<br>
   $post[hasaward]
</smallfont><br><br>
   <!---This was put here to see if $post[field7] would get to the page...it does
<smallfont>
   <b>CD I am Playing:</b>
   <br>$post[field7]</smallfont>
--->
<!---this should be what is displayed but it's not --->
[b]$cdnow[/b] 


So how do I get $cdnow to the screen???
