kiarocks, if an error says that something isn't found you need to assess why that is the case. Your code has: 
int actualAge = (age - (age % EpidemicWorld.ageRate) ) / EpidemicWorld.ageRate;
So, you are accessing "ageRate" as a class variable in EpidemicWorld (I'm assuming EpidemicWorld is the name of your world class). Does such a variable actually exist? Have you declared it in EpidemicWorld? Is it definitely a variable and not a method? (If it's a method you need to put "()" after the name to signify a method call). Is it definitely a class variable (declared as "static")? - if not perhaps you should be accessing it in a different way. My point is, just looking at the code where you get the error is not enough to tell what the problem is nor how to fix it. Can you also show the declaration of "ageRate" in the EpidemicWorld class?

#
kiarocks, you need to change all references to 'EpidemicWorld' and change them to 'InfectWorld'

no dan post, it is epidemic world on mine. and davmac, i have not declared it, danpost, whats in you world statement??

#
I have played around with it, and right now I have this declaration statement in EpidemicWorld 
public static final int ageRate = 5;
My EpidemicWorld begin like this:
import greenfoot.*;  // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
import java.util.*;  // (List)

public class EpidemicWorld extends World
{
    public static final int ageRate = 5;

    public EpidemicWorld()
    {    
        super(25, 25, 25); 
        populateWorld();
    }
Followed by 'public void populateWorld(){...}'

'ageRate' is the number of cycles that represent a year; I am thinking about changing it to '8'. 1) So they do not die off so quickly 2) Term-length (pregnancy) would be an even 6 cycles (3/4th of a year) Or, maybe better would be '12' (each cycle would represent a month; and 12 months is a full year); therefore '9' would be Term-length (pregnancy) in months (which is normal). Anyways, make yours whatever you feel comfortable with!

ok, ill see if it works

#
would the procreate method be void or boolean?
kiarocks kiarocks

#
and would it be public or private?

This is what i used in the Person class: 
    
    private void procreate(int procChance)
    {
        List<Person>persons = getObjectsInRange(2, Person.class);
        int maleCt = 0;
        for (Person person: persons) { if (person.sex == 1 && person.infectionStage < 2) { maleCt++; } }
        if (Greenfoot.getRandomNumber(100) < procChance * maleCt)
        {
            isPregnant = true;
            howLongTillDue = EpidemicWorld.ageRate * 3 / 4;
        }
    }
I used sex = 0 for female, and sex = 1 for male. Also, i checked to see if sex of Person 'act'ing on is 0 (female) before calling this method.
