Hi Norrnext,

We got this error when we test the payment. It is a staging website so you can modify anything you want.

https://dev3ttwb.nl/shop

Also we don't see the Mollie/Ideal logo on the cart page.

Kind regards,

Raoul

Hi Raoul,

1) Regarding error.

I think Mollie does not like the number format with comma inside. From their docs:

> A string containing an exact monetary amount in the given currency.

So there is no requirements or any restrictions, but in their example they use 1000.00

> The amount that you want to charge, e.g. {currency:"EUR", value:"1000.00"} if you would want to charge €1000.00.

Can you change from 1,500 to 1500 please and try again.

2) Mollie/Ideal logo on the cart page - do you mean Phoca Cart checkout page or Mollie Payment page?

Kind regards,

Additionally we can try to normalize the amount string in our plugin code to avoid such errors and handle numbers like 1,500.25 or 1.500,25 or 1500,25.

I see... Trying to understand why, because plugin just takes the amount from Phoca Cart order data and pass it to Mollie. At the moment cannot find anything in Phoca Cart settings that can format thousands separator with comma.

Is it OK to install https://www.phoca.cz/phocacommander - I need to debug Phoca Card order data?

Kind regards,

Whatever we change in the settings it keeps adding a komma to the 1000 so it will stay at 1,000

Totoweb

Yes, you can install the phoca commander plugin.

If we test a product of € 100,00 it works. € 1000,- not.

That is a thousand separator. Not sure from where it comes. Give me some time to debug :)

In any case we will implement the normalization of the amount string in our plugin code to avoid such errors and handle numbers like 1,500.25 or 1.500,25 or 1500,25.
