Custom Fee field in Dependent Field of Dependent Field displays but not in total

Custom Fee field is not adding into total:

Field 1 - this is a Master Field in the Billing Section -
Radio: Do you want to Add a donation? Yes/No

Field 2 - this is a dependent field set to display if field 1 is "Yes" and set as Custom Fee / Not Discountable
Radio: $200, $100, Other / Values 200 100 0

Field 3 - this is a dependent field set to display if field 2 is "Other" and set as Custom Fee / Not Discountable
Text: / Default Value: 20

All of the dependent field triggers work as expected, the user experience is good.

Any value selected in Field 2 DOES appear in total Amount - it works.

Choose "Other" for Field 2 and field 3 Displays as expected.

Any value typed into Field 3 is NOT being added into the total Amount

I have re-read the docs and forum posts, and confirmed that settings are correct.
Am I missing something or did I hit a bug?

Hello Duke

For this, we will have to check it directly on your site to see what's wrong (maybe with the custom fields setting) and get it sorted

So please submit a support ticket sending us:

- Super admin account of the site
- Link to that group registration form
- Tell us ID of the field which fee is not added to total registration fee

We will check to see why the error happens and get it corrected

Uploaded credentials as requested and published the problem field on the public site.

Thanks. We received your ticket. Our developer will check it and reply you via the ticket

Tuan

Any luck or are custom fees to add a donation in a dependent field not supported?

Hello Duke

Our developer could not login to administrator area of your site to check the issue. Could you please check and send us correct super admin account?

Please look at the support ticket for more details

Tuan

BTW, please help communicating via support ticket instead of via forum like this

Regards,

Tuan
