Help with Gravity Forms Currency Converter (Please!)

I am working on a donation form available in 3 currencies: USD (default), EUR, and MXN.

I’m using Gravity Forms and a PayPal Gateway.

In order to provide different donation amount options, I created a few radio buttons:


I also have a currency converter which works perfectly fine:


**There is only one problem:**

Whenever I change the currency from USD to another currency I want the “total” field to show the same “total” amount I had before, but in the newly selected currency.



If I select $15 as an option, and then change the currency to EUR, I want the total to show 15 EUR. Instead, what I get is EUR13.81.


Any insight would be greatly appreciated.


Thanks in advance!
