Freight calculator

Hi guys,

It would great if you help me with the freight calculator I am trying to prepare.
The table in the attached file will be hidden. My client should choose country and zip code (note that I will operate with around 10 countries) and based on the purchased item's weight [50 or 100 kg - I need kind of VLOOKUP formula here, because the weight can vary from 50 to 10 000 (more columns are coming)], I have to calculate what would the charges be.

Thank you so much!
