Returning values from on column in a row if another column in the row meets specific criteria

I want to be able to get values from a cell in one column if data in other column meets criteria. Please look at the picture then read further.

So I want to create one column to show all SRaverage values if column naziv sloja has text which says:

kora trošenja

And one other column to show all SRaverage values if column naziv sloja has text:

osnovna stijena

So I want to extract SRaverage values which are the ones for osnovna stijena in one column, and SRaverage values for osnovna stijena in other column.

Is there a way to do this?
