A $25 registration fee also acts as a donation.   Locking a donation amount in your donation form is very easy and can be found within the Form Builder tool, under the Fields & Layout section. You would want to open the box 'Donation Amount' and then add the default amount that you want donors to donate and you would toggle the 'Lock Field' option to be on, this way donors can only donate that specific amount.   ![Screen Shot 2022-08-15 at 1.06.34 PM](https://support.donately.com/hs-fs/hubfs/Screen%20Shot%202022-08-15%20at%201.06.34%20PM.png?width=688&name=Screen%20Shot%202022-08-15%20at%201.06.34%20PM.png)   -
