Not a problem at all. Whether you are looking to increase your pledge per challenge amount, decrease your pledge per challenge amount, or add/increase your flat donation; this can all be found in your dashboard. All changes made to your pledge per challenge amounts will only affect future challenges, not those already completed by the participant. If you have any questions on how to edit your donation amount, please contact a FunRaisen representative via email at support@funraisen.com and we will gladly assist.
