eCart UPS shipping - quote all items in cart as 1 unit?

Our eCart is set up using UPS shipping & currently quotes each item separately in cart, making an order of multiple items very expensive. How can I get a quote by grouping all items in the cart so they ship as 1 unit? FYI - all items utilize same box sizes and weights, so they should be very easy to group.
i.e.: a single item measures 4"x4"14", so 2 could go into a 8"x4"x14" box.

Please attach a copy of the confirm_cart,php and I can suggest what lines to update. Do you want a maximum of 2 items per box or assume they will all ship in one large box?

No maximum. All items will ship in 1 box, sized to accommodate.
Thank you.

Update line 32 from:
$Shipping_Packaging = 0;

to:
$Shipping_Packaging = 1;

Update line 58 from:
$Shipping_PackageArray[$Shipping_PackageIndex]["Quantity"] = "".WA_eCart_FormatNumber($jackitsCart->DisplayInfo('Quantity'), true, 1) ."";

to:
$Shipping_PackageArray[$Shipping_PackageIndex]["Quantity"] = "1";

That should make it treat everything as one package.

I made the changes you listed and its still not calculating correctly. If I put one item in the cart, the shipping is correct, $9.63.. If I put 2 is only 10.83 (way too low). If I put 200 in the cart, the shipping is $9.63 ??

If you go through the checkout process all the way up to submitting to authorize.net, but do not submit to them & then clear out the cart, the items clear from the cart but the shipping amount does not seem to. I think whatever variable is holding the shipping quote is failing to be reset (cleared) at places where it should. I'm wondering if that's not screwing the math up all over the place.

This is baffling, I can't find the issue. Is there a way to get the checkout pages to generate a log or XML file so I can track the values? Or do you have a plug in or code submitted by UPS to handle the calculations (which the cart should be sending the weight to them for a shipping amount)?

Thanks

Can I get FTP access? I'll take a look.

I sent you a private login.

That server IP address doesn't seem correct. I can't connect to it and can't even ping that IP address. Are you sure you entered it correctly?

Please see the attached.

I've looked at the files and they all look correct. What is the url to the site so I can do more testing?
