Could you please direct me where in this php file (zones.php), should I be looking for this empty string?
To address the specific warning message that was presented, the only thing necessary was to enter in a number into the handling fee area for each of the zones and not leave it blank. This entry is performed from admin->modules->shipping->zones.

It appears the code already contains a default value of '0' at least when first installing the additional zone(s).
