How to disable table rate shipping module after certain weight

How to disable the TABLE RATE Shipping module after certain weight?

I have few different package sizes and different table rate modules for them. Problem is when TABLE 1 is over 2000grams you have to ship using TABLE 2 rates. How ever it's still possible to choose TABLE 1 but the price is 0.

Hope you guys get what I'm after.

What are the settings right now in the Configuration ... Shipping ... for the Maximum Weight and the two Tare Rates?

Max weight: 10000 (grams)
Package tare small to medium: 0:3
Large: 10:0

And I have 11 different table rate modules for different countries and zones

Finland Letter
Finland Package

Europe Letter
Europe Maxi Letter
Europe Zone 1 Package
Europe Zone 2 Package

World Letter
World Maxi Letter
World Maxi Letter Economy
World Zone 3 Package
World Zone 4 Package

So I'm intrested if it's possible to code each table rate module in a way when the order is certain weight some of the modules wont be visible.

To disable at over 2000, you can use in the file:
/includes/modules/shipping/table.php

the code in RED:

    // disable only when entire cart is free shipping
    if (zen_get_shipping_enabled($this->code)) {
      $this->enabled = ((MODULE_SHIPPING_TABLE_STATUS == 'True') ? true : false);
    }

[B]if (!IS_ADMIN_FLAG && $_SESSION['cart']->weight > 2000) {
  $this->enabled = false;
}
[/B]    if ($this->enabled) {

Hi, this worked in zones shipping module too, thanks Linda!

Only one thing, I had to change the '2000' to '2' to make it work right. Not sure if zones consideres weight differently than tables does?

Also...perhaps this should be how the tables and zones modules are setup by default? On my site, if the total order weight went over the maximum set up in the zones settings, it would allow them to checkout with shipping price '0'. This doesn't seem right.

Thanks for the update that you were able to fix this ...

Most people are using the Weight as pounds for use with USPS, UPS and FedEx and 2000lbs would not work very well ... :lookaroun

For you, you are working in grams so you needed to adjust things for your purposes ...

If you are not adjusting your weights for grams vs lbs or are having difficulties in setting your weights and obtaining quotes you may wish to re-review your shipping or expand your explanation about your shipping methods and customizations ...
