I have a street network with the average slope for each street segment in a column. Now I want to use this column to calculate the average slope per route. Thus I think would like calculate the average of the slope column in the field evaluator. Is that possible?

I tried already to put the value = Avg (???slopecolumn???) but it didn´t work.

Thank you in advance,
