.. Show reduced price option only on condition?

[Anonymous]

Hello again,
We have different Ticket prices depending on the wealth of the attendee. I would like to show the reduced price only if the person answers “yes” to a placeholder on wealth we like to request. Problem is, I can only do this if I put the lowest price option into a custom form. This then produces an Error saying that I need to have all price categories in #_SEATS in the booking form.

Can you tell me how I can make conditionally show or hide a price option? Attendees shall only be able to book one single place at a time.

I’d do it using custom fields with the “extra price” option checked (use a negative amount as value and some text as “tag”). Then you can also use #_DYNAMICPRICE in your form and the price will get adjusted automatically if people e.g. check a certain box.

That sounds good! I found the extra price option. However I could not find in the docs how I can set the value of (positive or negative) price to change the dynamicprice. Could you help?

That is the value of the custom field
