$numberRegistrants * Custom Field

Yes. It should be possible in latest version. However, with a clever setup:

1. Assume that name of the field is eb_volunteering

2. Set Fee Field to Yes

3. Set Fee Values to

0
200

3. Set Fee Formula to [EB_VOLUNTEERING ]*[NUMBER_REGISTRANTS]

Then check it again, it should work

Oups, I tried with [FIELD_VALUE ]*[NUMBER_REGISTRANTS] ! :silly:

It's work with [EB_VOLUNTEERING ]*[NUMBER_REGISTRANTS] !

Thanks.

Tip: Be sure to have fee formula in upper case!

Yes, that's correct. The tag used in formula needs to be in upper case
