This option by default is set up to charge your card only once. You can change this by choosing a selection from the drop down menu which would allow your card to be automatically charged for a period of time you choose. When using this recurring donation option your card will be charged according to the settings you choose. For example, if you want to have your card charged each month for 5 months you would enter a 4 in this field because your card will be charged 1 time when you finish the application and that charge will be repeated 4 more times.
