I am getting this error when I try to check out in my store

Warning: Smarty error: math ``price*amount'' in ``customer/home.tpl'': parameter ``price'' is empty in /home4/pluckype/public_html/store/include/lib/smarty/Smarty.class.php on line 1092

I did some searches and still have no answers. Does anyone know what this means?
