 * I have a website shop (www.heidiline.com) using WordPress eCommerce, and whenever
   anyone attempts to purchase something and goes to the shopping cart/checkout,
   there are at least 8 of these messages all over the page: ‘Warning: a non-numeric
   value encountered in /home2/heidilin/public_html/wp-content/plugins/wp-e-commerce/
   wpsc-includes/cart.class.php on line 987.’ Needless to say, folks don’t want 
   to purchase anything when they see this. I would appreciate any help on this.
   Thank you!
 * By the way, to temporarily resolve this, I dialed back the PHP to version 7.0
   and that seems to work. This problem only occurs with versions after 7.0
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fnon-numeric-value-warning-3%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_
