Which widgets can have incentives

• Only Transacción (Transaction) widgets, that is, forms with amounts to choose from. Product, peer to peer and other form types don't appear in the list.
• Each form can be in only one campaign with gifts. If you already use it in another one, it shows as "En uso en la campaña…" (In use in the campaign…) and you can't choose it.
• Gifts are offered in your organization's currency. If the form accepts other currencies, people who donate in another currency make a regular donation, without a gift.

You don't need to edit your forms: once you choose them in the campaign's Incentives tab, the gifts appear on their own, right below the amounts.
