Use the following instructions if you want to create links to your donation pages with pre-chosen amounts. For example, if you're running an email campaign where you have a button saying "Donate $250 Today!"
If you're using a native NationBuilder donation page (as opposed to linking out to an external processor):
The URL you'd use for that link would look like this (go ahead and click the link to test it out):
http://megatheme.nationmedia.io/donate?amount=250
Generally, the format is as follows:
{{ your_donation_page_url }}?amount={{ pre_chosen_amount }}
NOTE: Don't include symbols ($, €, £) or commas/periods in your {{ pre_chosen_amount }}.
Incorrect Examples
http://megatheme.nationmedia.io/donate?amount=$2,500

Correct Example
