Invalid Amount Response

Using UK Payflow.

 

Perhaps someone can advise me.  I am running an application (ZenCart) successfully.  I have a development version of the same site running on a separate server to work through the issues of php versions. Paypal Express has worked fine on the site for many years. I am in the process of fault-finding the installation on the development site.  When I attempt to initiate a connection I receive an "invalid amount" response like this:

 

RESULT=4&RESPMSG=Invalid amount&REQUEST_ID=1570476410&CURL_ERRORS=

 

When I investigate the data that is sent by cURL, it seems that there is a valid amount.  In array form, for instance:

 

Array
(
[PAYMENTREQUEST_0_AMT] => 0.47
[PAYMENTREQUEST_0_ITEMAMT] => 0.47
[L_PAYMENTREQUEST_0_NUMBER0] => PC-UNTM

 

 

Can someone advise whether there is some other cause of this response - for instance, either an authentication error or a Payflow error of some type? Also, is there a way of finding further information about the response? Can I contact Paypal and simply ask them why this response was generated? If so how?
