My paypal not working with large transactions

Hi,

I sell engines, so the prices are over $1,000 US, and I had been getting the following error (I am in Sandbox mode)

10413 Transaction refused because of an invalid argument. See additional error messages for details. - The totals of the cart item amounts do not match order amounts.

I have searched high and low on these forums, read all the threads, applies patches and settings, still nothing

I also charge a flat rate shipping charge, and sales tax for customers in the state of Texas

I created a test product at $25.00 and did a test transaction (that included flat rate and sales tax) and it went through perfectly

Then I increased the price of that same test product to $1,200 and tried the transaction, and I got the same 10413 error. So it looks like it's not wanting to accept those large payments. What's the deal? How can I get this to work? I am about ready to pull my hair out with these issues

Thanks

I'll assume you've searched for that error number, and 'paypal 1000'. Have you seen post #80 here?

What version of Zencart are you using?

Hi thanks for the quick reply

I have looked through many of the 10413 threads and dozens of pages.. I haven't searched for Paypal 1000, is that an error or a common problem with large transactions? I will look into it

On reply 80 in the link you provided, he is suggestion to not include tax? I'm not sure I follow what he is suggesting - But like I said, I was able to complete a transaction at $125.00 (including flat rate shipping and sales tax) but when I raised the price of the same product over $1,000 I got the same errors

I am using Zen Cart 1.3.8a

I tried implementing the changes on this thread

Still getting the error message

Not sure if this is right or not, but when I do a transaction it's creating 9 different logs... How do I know which ones to look at?

Hi DrByte,

I had tried that previously and it did not work. From reading through dozens of threads I've noticed you seem to be the resident expert, so glad to see you're here :D

I would like to post my logs of the successful transaction and the logs of the failed one, so they can be compared, but like I said, it created 9 logs, I have no idea which to post... Need help on this, need to get it fixed

Thanks

Zip them all, upload the zip to your server, and PM me with a link to that zip file.

What order-total modules do you have enabled on your site?
For some reason the match is triggering a catch-all handler due to mismatches in calculating details for submission, and that catchall is failing in some cases. Normally the catch-all (HANDLINGAMT) should never be submitted because it should calculate to 0. But yours isn't, so that means you've got something that's interrupting the math calculations.

I have ot_subtotal, ot_tax and ot_total

the others are disabled

What about ot_shipping?

What addons have you added to your site?
What kinds of customizations have you made other than cosmetics?

ot_shipping is disabled

Other mods I have installed:

Super Orders
SEO URLs
Easy Populate
Image Handler
Orders Export
and M1 Performance Module

I also added a customized drop down menu as a sidebar

I think that pretty much covers it

So, you're charging "flat rate shipping", but you have ot_shipping disabled? That's going to mess up calculations, and could very well be the cause of your problems.

No, I was getting the error before I disabled it (I was following a thread which mentioned disabling some of these)

I just enabled it and tried a transaction, no dice

Did you notice anything else odd about the logs I sent you?

The only glaring issue was that it's triggering the catch-all handling, which tells me that something is messing up the regular mathematics validations and the system is attempting to come up with numbers that will work in order to be submitted without being rejected because they don't add up right. In most cases that's a result of additional unexpected order-total modules or odd discounts.

Could it be that most of the items have a special price?

For example, here is a link: http://tinyurl.com/ylpbsdr

Perhaps, but unless you've got something that's calculating specials prices outside the way Zen Cart normally does, that shouldn't affect the PayPal content preparation.
