This is the XML-RPC server configuration page.
Here you may define the maximum and minimum values for the addition or subtraction exposed services.
If the result of the operation is lower than this value, a custom XML-RPC error will be returned: 10002.
if the result of the operation is bigger than this value, a custom XML-RPC error will be returned: 10001.
Use the XML-RPC Client example form to experiment.
