Collection Display Price

[C_Work]

 I have some complicated products that are multi optional designed by the customer. We are talking Lengths, special attachments, types of materials. I am forced to use a third-party app fo this. I have tried quite a few and the "dynamic product options" app by itorrus seems to have all the options I need. I have one problem though

The product price displayed on the collection page is $0 no matter what I do. 

Does anyone know of an app or a way I can adjust the "display price" on the collections page? I can't have all my products display as $0 it's pretty frustrating.

Hi There!

Do you have a base price for those products? If yes, you can then modify the collection template to show "From 20.5$" instead of "0.00$"..What do you think?
