Every organization will have a default currency set on the Organization Info page. Set this to your preferred default currency, as shown:
For each donation campaign, you can also change the currency to be different from your default currency.
To do this, start by clicking the "Edit Campaign" button for your campaign.
On the campaign editor page, click the "Edit Form" button to reveal the drop-down menu. Then select "Amounts" from the options.
Find the "Donation Currency" heading at the top of the following page and click the drop-down menu under currency to select your preferred currency.
You can also enable our multicurrency donation form feature to add multiple currencies to your form.
Finally, click the "Save and Preview" button below or "Next" for the changes to go live.
