new 8 zone shipping mod help Please??

I am in the process of converting oscommerce mod that calculates shipping cost by percentage of cart amount and the zone in which you live according to SMC.

I have converted mod and it shows up in admin fine and installs, however when the customer arives at estimated shipping cost and checkout page they receive blank page.

When I check debug mod I receive following error:

[09-Jul-2008 16:46:29] PHP Fatal error: Maximum execution time of 60 seconds exceeded in /home/greatcan/public_html/catalog/includes/modules/shipping/smc.php on line 113

line 113 reads: $dest_zone = $check['shipzonecode'];

below is the complete mod:

```These two lines need to be reversed.  ie: the closing brace for the while() statement needs to come *after* the MoveNext() call, otherwise you end up in an endless loop.

thankyou mod now installs and I am able to configure but shipping charges don't show, It tells me shipping not available to selected country

no errors show up in error log or debug mod

Script was converted from osc mod so I am thinking it has to be a bad variable or missing function but I would think I would get a php error somewhere

Anyone have any ideas??

Thanks Guys in advance

Not sure if this is the specific cause or not, but something I noticed while looking at the code you posted earlier was:$order_total = $cart->show_total();should be:```
$order_total = $_SESSION['cart']->show_total();

And you don't need $cart listed in your "global" statement earlier in the same function.

Thanks to Dr Byte I finally got it to work, now to only tweak it then it will be ready for distribution.

THE FEATURES OF MOD ARE:

1. Shipping Rate is determined by destination zone according to UPS and DHL 7 Zone zipcode freight chart. Easily
   configurable to other countries and different shipping charts.
2. Zipcode Zone determined by MYSQL driven data base.
3. zipcode table easily convertable to most countries
4. handles shipping by percentage or flat rate
5. Number of Zones are adjustable set to 7 by default
6. Start zone is configurable 2 by default
7. Can have more than 1 percentage or flat rate per zone
8. handling rate can be added to each zone
9. Mod doesn't modify any files in ZenCart.

If interested in such a mod
leave me a message

Did you ever get a working Mod??

I am trying to setup the same SMC scenario

Could really use some direction and help

Did you ever get a reply to your request for info on the modified Mod? Also using SMC so very interested.
