Help with VLOOKUP formula

I'll try to explain this as simple as possible:

I have attached a combo box, and in it I have the option to select three materials. Each material has its own characteristics (strength, hardness and density).

Now, I' want to choose one of these three materials and by choosing one I want his properties to automaticlly fill in particular CELL's.

To be clear here is a picture:3

....... So in the three bordered cells I would like to automatically see the material properties of P235 .... 100-120-150

Thank you


EDIT: the words are Croatian and the meanings are : Čvrstoća-strenght; tvrdoća-hardness; gustoća-density
