When running an A-thon fundraiser, you can set limits for the amount that donors can pledge per-unit for any activity. While donors will still be responsible for pledging a per-unit amount they feel is appropriate, some campaign organizers find establishing limits is helpful for offering some general guidance to donors. To do so, follow the steps below:
Go to my campaigns in the left menu.
If you have chosen list view, click on the title of your campaign. If you have chosen grid view, click on the campaign image.
Click A-thon in the timeline at the top.
Click edit on the activity that you would like to add limits to or click create an activity.
Click more options.
Click the box next to create preset per-unit pledge amounts for donors.
Click the box next to set min and max per-unit pledge amounts.
Enter the minimum and maximum amounts.
Click save at the bottom of the box.
