Offer discount for ordering certain amount of products - coding help!

[#1]

I am trying to set up a conditional statement that goes like this: If a customer selects 6 or more products from a list of all possible products, then they will be offered 10% off of their subtotal. I have a field set up to calculate the "Total Quantity" of products ordered and a field for the "Subtotal". I then have a field set up for what the discounted price shoud be, once the 10% is taken off - "Discounted Subtotal. 

I have tried with no success to set this up correctly. Any help/ideas would be greatly appreciated! Thanks!

Hi,

Can you share in greater detail the steps yhat you've followed?

And how big is the list of items that the user selects from? Does the user selects these items from a dropdown menu?
