Pricing Packages Exclusion

Afternoon,

I have set up 3 pricing packages:

1 – Basic
2 – Silver
3 – Gold

I have excluded several of the features in the Basic package (e.g phone number not allowed) that you are only able to have in the gold and silver packages. When excluding these features, however, they are removed from the basic package listings form.

Are there any settings that allows me to include these excluded features in the basic listing form but when some one tries to input data into the excluded field, it says that these fields are for paid packages only (or similar)?

Many thanks

Nigel
