Please let me know if you have any other questions.
I am trying to create the value to match on. We have the same fee for a few different Reg Units (Virtual Participation and the 5k Walk are both free), and it is telling me I can only use $0.00 once as a match. I'm not sure I understand this.
Note: I think I figured this out
For this dictionary, the Values to match on will be your unit and the Replacement values will be the fee amount.
