Conditional Logic Set Prices

[UHA-Abby]

I'm using the Globo Product Options app for my product listings and need help setting up conditional logic with fixed prices. I want customers to choose an option, like 'Classic Bow,' and then select a size. Each size should have a set price (not an additional cost added to the base price). How can I set this up so that the price for each size is displayed upfront, based on the size they choose?
