Change currency of #total_amount

Hi, i’m about to buy your plugin but i’m currently looking for a way to change the currency from “$” to “€” when using the placeholder “#total_amount” wich is by deffault showing in dollar but i’m not finding anything about this in the configuration pannel. Is this possible to do or is that only permitted in the complete version of the plugin ?

I Hope you understood what i need ??

Thanks a lot.
