USPS Shipping Module by MarcoB - RateV4, IntlRateV2 - Support Thread

I just tested my cart functionality and something may have changed on the USPS server end.

I am not seeing any box size removed when I add items that I know are too large.

Since I just moved servers overnight, so I may have a glitch caused by that.

oh boy! that's not good news =o(
No wonder it wasn't working properly.

Try changing the weight to

0.312500009

I think you may have too many zeros. I think the original example was meant to show decimal places to the right and not necessarily number of zeros to the right of your weight.

This is my weight for a 1/10 pound item 13 cubic inches
0.100000013

My second site is functioning correctly, so I have some work to fix the site which had a server move last night. DARN

Too many zeros?...

Ok, this is what the instructions say on the actual usps module which are different from the instructions found on the file included with the module:
"Volume is set in digits 6-11 after the decimal point in the products weight field.
eg: Product A weighs 1.25lb and is 689.3 cubic inches so,
Product A Weight: 1.25000068930"

My weight is for a 5oz item (0.3125) 9 cubic inches.
So if the volume is supposed to be set on the 6 digit after the point, it should be 0.3125009 (right?)
So I tried that and same result.
If I add 2 products to the shopping cart everything shows fine, as soon as I add one more product the small, large and medium rate options disappear.

Sorry made a mistake.
With the new weight you suggested (0.3125009) the small rate option doesn't appear anymore, even if I just have 2 products in the shopping cart.

Maybe we need some new math.

A small FR box will hold 70 cubic inches which is embedded into the module. If you are using 9 cubic inches per item, there's a problem.

If 3 will fit into a small FR box and the 4th requires upgrade to either Large video O-1096L box, Med FR or Regional A FR box, then logic suggests that the volume of the items should be something like 20 cubic inches so that 3 will fit and the 4th goes over 70 cu inches.

0.312500020

You did install the SQL patch, didn't you?

That's why I used my example product. I know that 5 13cu in items will fit in a Sm FR and the 6th requires upgrade to the Large Video O-1096L box.

Yes, I did install the SQL patch and uploaded the admin>modules.php file

The logic makes no sense whatsoever.
if 3 items of 20 cu in gives the correct options, so should 3 items of 9 cu in.

I entered your weight suggestion (0.312500020) same result.

This time I tested further and found something weird happening.
If I add 1 item with my original weight configuration (0.31250000009), small, medium and large FR don't show.
If I add 2 items with my original weight config. small, medium and large FR show!
If I add 3 items, S,M,L FR disappear again.
If I add 4 items, S.M and L FR show up again!

This is the weirdest thing!

i think that your volume is too small ( 0.31250000009 ) is 9/100 cubic inches and is confusing the calculations. I never looked at the documentation. I added/subtracted zeros until it worked. I'm not sure that your 4 decimal weight may not be causing an issue. You might try rounding 0.3125 to 0.3 pounds and add zeros to get the right volume.

Try using the weight that I use for my product and see if anything changes when quantities 1, 3, 5, 6 items are placed in the cart.

I'm not a coder. Just a user whose site is using this shipping modules without any issues.

My earlier issue today of non-functionality was caused when I reinstalled the module, I forgot to toggle the "Filter by Volume" button.

I just realized that you said 1.3.8 and the module was written for 1.3.9 and may not be backwards compatable.

I have just installed V1.5.0 and there is no USPS in the shipping module.
What do I do now.
I am very familiar with USPS Shipping but I am New as you can be with Zen Cart.
Can you tell me how to make USPS available on my store?
