Zone shipping limits

[aray]

help!

I have zone shipping set up. I’ve input zone table values (1:5.00, 4:10.00, 15:18.00, ….) but I am limited to how many I can enter in this field (255 characters).

 

I want to set values up to a certain weight – say 250lbs and have nothing after this, no high value. I want the program to say “Shipping cannot be determined….blah blah blah” (which I can set in the zones.php language module) when someone orders products over 250lbs and not give them the radio button option of $0 value for shipping.

 

I added this additional line of code from the add on update which is supposed to prevent this from happening: if ($shipping == -1) $this->quotes['error'] = MODULE_SHIPPING_ZONES_UNDEFINED_RATE;

 

But, it doesn’t seem to do anything, i.e. if someone orders products over 250lbs they get a shipping value of $0 AND the radio button option of choosing this value! In addition, it isn’t pulling the text from the zones.php file in the languages module.

 

Any idea what I could do to fix this or why is doesn’t seem to be working?
