Advanced Cost Shipping max price

Hi there, I’m just setting up an advanced rate shipping so that each item adds more to the shipping price, however I’d like a maximum shipping price so it doesn’t keep going up and up. I can see on the woocommerce documentation it explains how to it when your using percentages but it doesn’t say when you doing it with the quantities.

For example here is what it says on the documentation –

“vailable placeholders:

[qty] – Number of products in the cart
[fee] – An additional fee. This fee has two optional arguments.
percent – A percentage based on total order cost.
min_fee – A minimum amount. Useful when using percentages.
max_fee – A maximum amount. Useful when using percentages.
Examples
10 + ( 2 * [qty] ) – A base shipping cost of $10 plus $2 for each item in the cart.
20 + [fee percent=”10″ min_fee=”4″] – A base shipping cost of $20 plus 10% of the order total, which is at least $4.”

I’ve made a few guesses on what I thought might work, but it doesn’t. If anyone could suggest coding that would work, it would much appreciated.

Many thanks

Yelena.
