Netlogo error message "people-movement in a observer context because people-movement is turtle only."

Question

I keep getting this error message for fro my people-movemnt. I looked at my code which is trying to create water demand in a city. I couldn't figure out how to fix the code. I am trying to copy how people would move from home to work. I am trying to check the setup of people so the code is not finished but it won't let me check until I fix the ticks. Here is the code that deals with people-movement.

to setup-people
  ask patches[
  sprout-people population
  ask people[
        if random 100 < percent-female [set is-female? true]
   ask people [
    set random-number random 100]

    ask people
    [if random-number <= 31 [set age 10]]
    ask people
    [if ((random-number > 31) and (random-number <= 37)) [set age 25]]
    ask people
    [if ((random-number > 37) and (random-number <= 50)) [set age 35]]
    ask people
    [if ((random-number > 36) and (random-number <= 75)) [set age 45]]
    ask people
    [if ((random-number > 75) and (random-number <= 81)) [set age 55]]
    ask people
    [if ((random-number > 81) and (random-number <= 87)) [set age 65]]
     ask people
    [if ((random-number > 87) ) [set age 75]]

  ]]

end

      if age >= 18
      [ let cbd-pickup roads with [is-school? and not is-intersection?]

  let residential-pickup roads with [is-high-residential? or is-low-residential? or is-mid-residential? and not is-intersection?]

  ]

  ; destination location coordintes
  let destination-xcor1 [d-xcor] of self
  let destination-ycor1 [d-ycor] of self
  setxy d-xcor d-ycor
end

I looked at all the different setup and go codes. I tried to ask people in daily activities but I think that would be an observer code so I tried to take that away but that doesn't change anything. This step is trying to move people depending on the time and the probably on a slider.

Answer 1

It is hard to know exactly, as you haven't included the portion of the code that calls people-movement. However, people-movement calls setup-daily-activities, which refers to a variable called age. If age is in fact a turtles-own variable, then setup-daily-activities (and thus people-movement) has to be called by a turtle, as the error suggests. (The rest of that procedure also seems to refer to things that a turtle would do.) Check to see where people-movement is called and check back if the answer is not obvious.
