Hi guys, me annoying again ;) My problem is that this code does not increase the int value of a given index, its in a button class that should get covered green if its clicked, the more often it is clicked, the more green the button should get! 
if(index!=0)
        {
            getImage().setColor(Color.green);
            getImage().fillRect(0,0,(getImage().getWidth()/10)*UserInfo.getMyInfo().getInt(index),height);
            
            getImage().setColor(new Color(155,0,0));
            getImage().drawString("Cost: "+UserInfo.getMyInfo().getInt(index)*10,getImage().getWidth()/2-fm.stringWidth("Cost: "+UserInfo.getMyInfo().getInt(index)*10)/2,height/2+fm.getHeight()/4);

            if(Clicked())
            {
                UserInfo.getMyInfo().setInt(index,UserInfo.getMyInfo().getInt(index)+1);
                UserInfo.getMyInfo().store();
            }
        }
The code of Clicked just simply: 
public boolean Clicked()
    {
        if(Greenfoot.mouseClicked(this))return true;
        else return false;
    }
Thanks for help again!

I think you need to create a local field to hold the UserInfo object, change it, then save it: 
// to replace lines 11 and 12
UserInfo ui = UserInfo.getMyInfo();
ui.setInt(index, ui.getInt(index)+1);
ui.store();
Also, you must make sure that the user is logged in before doing the above, by using: 
if (UserInfo.isStorageAvailable())

uih you are right i had to store it local in a UserInfo variable, thanks again danpost ;) by the way what does getMyInfo() return if the user is not logged in?

That is something you could test and figure out yourself: 
System.out.println(""+UserInfo.getMyInfo());
Before running, go to 'Edit>Preferences.." on the menubar and clear the username field (Player name) at the bottom of the Miscellaneous tab.
