Hi,

I followed this instruction: [https://developer.squareup.com/docs/payment-form/payment-form-walkthrough](https://developer.squareup.com/docs/payment-form/payment-form-walkthrough)

But I’m failed and have no idea on where to check the log. Please advice. Thanks!

Hi @Yulia welcome to the forums!

Can you clarify where you’re seeing the error 500? The code in the walkthrough should be printing out the successful payment or the error, I believe. Feel free to provide your Square app id and I can try taking a look at the logs on our side as well.

Hi sjosey,

This line below popups the failure status.  
alert(‘Payment failed to complete!\nCheck browser developer console for more details’);

And I checked the console. it shows

My square app id is sandbox-sq0idb-b0c0E9guIyHD3POQu-x5Fw

Thank you! Really appreciate it!

If you expand “result” it should show you the cause of the failure. Looking it up in our logs, though, the error is:

```auto
"This business can only process payments in AUD but amount was provided in USD."

```

so you need to change “USD” to “AUD” in the `CreatePayment` request.

Thank you!!! Totally ignored there was an “expand” symbol…
