If you're just wanting to look at the slope, then the basic idea is to categorize the slope values and assign them an associated cost value. For example: Slope 0 - 5 could have a cost ...

Here's a different approach. Since you mention that the raster layer "Helning" has the correct values, you can extract the values from this layer. Use the Centroids tool to create a new point layer from the centroids of the Gradient Vectors layer. Use the Sample raster values tool to copy the raster values into the attribute table of the point layer. Label ...
