   I've set up posts to have several relevant custom fields.
   each post may use a few or all of the fields that i've set up. however when a post has no need for some of the fields and i have not used them, i can see an error message appear for that particular line on the page.

   i have added a conditional statement for each but the error message seems to still prevail.

   the code looks something like this

   <?php
   									if (empty ($custom_fields) )
   										{
   											echo "";
   										}
   									else
   										{
   											$custom_fields = get_post_custom();
   											$Track1 = $custom_fields['Track13'];
   											foreach ( $Track13 as $key => $value )
   											echo  $value . "<br />";
   										}
   							?>

   and the error i get is like this relating to the foreach

   Warning: Invalid argument supplied for foreach() in /content/BusinessHostPlus/b/u/burntprogress.com/web/promo/wp-content/themes/burntpromo/single.php on line 260

   any idea what i'm doing wrong?

   Um, typo?

   You assign a value to $Track1 and then you try to use $Track13 in your foreach statement.
