USPS shipping check out error

I tried the testing setup for USPS shipping as follow

ShippingRateComputationMethod.USPS.DefaultShippedFromZipPostalCode :20022

ShippingRateComputationMethod.USPS.Password: mypassword

ShippingRateComputationMethod.USPS.URL : http://testing.shippingapis.com/ShippingAPITest.dll

ShippingRateComputationMethod.USPS.Username: myusername

in the product variants, where the Weight [lb(s)]: I set the Weight [lb(s)]2

I created a testing account with zipcode 20008
I use the testing account to check out the product that i set the Weight [lb(s)]: 2
and come up this error:
USPS Error returned: Error Desc: Please enter a valid weight in pounds. USPS Help Context: 1000440.
how do i fix this error

thank you for your help

Ensure that a product that you purchase is ship enabled. Try weights 5 and 10.

P.S. Zip from should be set to 10022;

I'm having the same problem.

"USPS Error returned: Error Desc: Please enter a valid weight in ounces. USPS Help Context: 1000440. "

I tried what you told me do this here, but no luck.

Please help

I'm having the exact same problem with my USPS test account. Is there any reason to fool around with a test account?

Here is one set of test data that will get you by the error message.

<RateV2Request USERID="xxxxxx">
<Package ID="0">
          <Service>All</Service>
          <ZipOrigination>10022</ZipOrigination>
          <ZipDestination>20008</ZipDestination>
          <Pounds>10</Pounds>
          <Ounces>5</Ounces>
          <Size>LARGE</Size>
          <Machinable>TRUE</Machinable>
     </Package>
</RateV2Request>

Here is the web site URL http://forum.systemsmanager.net/lofiversion/index.php/t981.html
for a better examples.

I just set

         <ZipOrigination>10022</ZipOrigination>
          <ZipDestination>20008</ZipDestination>
          <Pounds>10</Pounds>
          <Ounces>5</Ounces>
          <Size>LARGE</Size>
          <Machinable>TRUE</Machinable>

and was able to get a response from the USPS server .

                                                                                                       Thanks,

I just upgraded to a production account and everything works. Don't bother with the test account.

USPS Error returned: Error Desc: Please enter a valid ZIP Code for the sender. USPS Help Context: 1000440.

Any ideas on why this is a problem? I setup a UPS account also and that works...
Everything seems right in configuration. I tried both ZIP code versions: 34232 and 34232-2486

If you are using the USPS test server you have to use 10022 as the origin zip code.

Thanks for the reply,

I am using: http://production.shippingapis.com/ShippingAPI.dll
Not the test server...
???

Try this known good data

<ZipOrigination>10022</ZipOrigination>
          <ZipDestination>20008</ZipDestination>
          <Pounds>10</Pounds>
          <Ounces>5</Ounces>
          <Size>LARGE</Size>
          <Machinable>TRUE</Machinable>

If this does not work send a email to the USPS technical section. They have to switch something  on the server before you go live.
