Hide price and "add to cart" for unlogged in combinations table

Hi, I purchase your module "Combinations Tab Pro" phew month ago - it is very good but i have a situation :)... What i can do to hide prices for guests/visitors from the combination tabs ? and also i want to disable the "add to cart" button for guests/visitors - In this moment i hide all prices from website for guests/visitors but if i have products with combinations the prices are showed. Thanks and wait your soon and kind reply, best regards Dragos

Hide price and "add to cart" 

Hello,
According to your questions - combinations tab module has two options:
"show price for logged users": https://i.imgur.com/X6R3u6A.png 
"add to cart for logged users" https://i.imgur.com/drrDAa9.png 

in effect the price will be visible only after log-in, as well as "add to cart": 

best regards,
milos
