I get an error when transferring from my store to PayPal. I am using odoo v9 and setup PayPal as per https://www.odoo.com/documentation/user/10.0/ecommerce/shopper_experience/paypal.html.

ERROR https://www.paypal.com/webapps/shoppingcart/error?flowlogging_id=21cabe1ad343d&code=AMOUNT_ERROR&mfid=1522967982642_21cabe1ad343d

I am using AUD currency, could this be an issue?

On the paypal forum is says this error is due to the amount being passed. but I can not find how to change this anywhere. https://www.paypal-community.com/t5/PayPal-HTML-Buttons/Anyone-what-this-means-webapps-shoppingcart-error-flowlogging-id/m-p/1230105#M632
