i comed up with this code, but it only calculates the sum of the posts on that page or category
$factorTotal = 0;
$factorCount = 0;
while ( have_posts() ) : the_post();
$factorI = get_field(‘price’, $post->ID);
if($factorI){ // Only if it exists
$factorTotal += $factorI; // Add it
$factorCount++; // Count it
} // end if
endwhile;
echo ‘Total Value: ‘. $factorTotal .’ $’;
I need it to calculate the sum of custom field ‘price’ that is in all of my posts
