create levels in Fundraising


I would like to create predefined donations for a fundraising project. I created the project, set the goal and instead of creating levels the next option down is to create rewards. I cannot find how to create levels of predefined donations.

i.e. someone donating a prefixed amount $ is rewarded $$$ woth of health care

and another donating $$$ is rewarded $$$ woth of health care.

kindest regards, Dirk Lovink
