Custom Field add fee not calculating

Hi:

We have been using membership pro to help us sell advertising space in a guide. It allows us to use multiple discounts, upload of files and some other nice features with layout.

We want to add a spot whereby after a visitor has chosen the ad plan they want, when they are in the form and payment area, they can select a box or dropdown that will add an additional fee of $25 to the price. We are using custom fields. HAve tried to use both dropdown and radio button.

The name is: osm_Map_Spot
We set the values at "Yes" (as in yes I want to have this add on)
Enabled "fee field"
Set Fee value at 25
In the fee formula we have tried: [OSM_PRICE]+25 and [OSM_GROSS_AMOUNT]+25 and [OSM_PRICE]+[Yes] ( as this is the field_value)

None seem to adjust the price in the in the Payment Form area.

We would appreciate any help. I am certain this is user error but do not understand the mechanics. Thank you.

Hi

At the moment, the custom fee field feature doesn't work very well. The fee will only be calculated on the payment process, it is not updated on the registration page yet.

For the settings of your custom field, it is wrong. You don't need to enter the fee formula, just leave it empty. However, as I mentioned before, the fee will only be calculated on payment process, it is not updating directly on the subscription form.

Regards,
