Beginner question: Value in object changes between update() and draw()

Hey all! I have an issue that's been bugging me all day. The code is quite verbose, so I'll try explain using just a snippet. Basically I have a class called Location where the update() and draw() methods are receiving a vector of user coordinates as input. In update() it's for calculating number of users close to each location.

    void Location::update(vector <userCircle>& users){
        noOfUsersClose = 0; // reset number of close users
        int closestDist = 40000; // basically just a high value
        for(userCircle u : users){
            if(ofDist(coordinates.x,coordinates.y,u.coordinates.x,u.coordinates.y) < distanceThreshold)
            {
                noOfUsersClose++;
            }

            if(ofDist(coordinates.x,coordinates.y,u.coordinates.x,u.coordinates.y) < closestDist)
            {
                closestDist = ofDist(coordinates.x,coordinates.y,u.coordinates.x,u.coordinates.y);
            }
        }
        cout << ofToString(noOfUsersClose) + "\n";
    }

When I print the noOfUsersClose here, I get the desired result. If no users are close it prints 0.
In the draw()-method, however, I print noOfUsersClose as the first thing and no these values change.

void Location::draw(vector <userCircle>& users)
{
    cout << ofToString(noOfUsersClose) + "\n";

It's a global variable assigned in the header-file. Am I somehow assigning the value of the integer wrong?

Hope to hear from you!
