Question about the custom fields

[jschuurkes]

Hello,

I have a question about a possibility for the custom fields of a product.

I'm working on a Bakery markt webshop and I have this problem.
I made a custom field for the customer to decide, if he wants a whole or a half cake. That works fine also with the price setting.
However, and that is my problem, a specific ingredient for a whole product has an additional price like 4,00 euro and of course for a half product 2,00 euro.
So, is there a possibility to enable/disable certain customfields after selecting the first custom field.
like:

Customfield (Whole/Half cake)

                 When Whole Cake then --> Customfield (soft bottom + 4,00 euro)

                 When Half Cake then --> Customfield (Soft bottom + 2,00 euro)

I now made a custom field with a list of whole and half soft bottoms, but I would like to use two different customs fields and let them come up thru the decision of the
Customfield (Whole/Half cake)

I hope that I made myself clear about my problem.

Thanks for any help,

Jack
