Displaying custom fields and thumbnails of posts in category

Hi

I’m close to solving this but think my php is letting me down.

I’m asking wordpress to loop through and echo the thumbnails and custom fields of various posts in a certain category.

It spits out the correct thumbnails from all the posts in that cat’ but only gives the custom field from the current post.

Here’s the code – please can some tell me where i’m going wrong!

`
$result = “<div>”;
$catposts = get_posts(‘category=8&numberposts=100&order=ASC&orderby=title’);

foreach($catposts as $single):
$customField = get_post_custom_values(‘blue_title’);
$result .= “<a href='”;
$result .=get_permalink($single->ID).”‘><img src='”.p75GetThumbnail($single->ID, 85, 58).” style=’border=none’ />$customField[0]”;
endforeach;
$result .= “</div>”;
echo $result;
