Unfortunately, you must remember to check the 'Include source code' checkbox every time. Am looking at it now.
public void saveLevel()
{
if(UserInfo.isStorageAvailable())
{
UserInfo myInfo = UserInfo.getMyInfo();
String level = myInfo.getString(1);
if (level.charAt(0) == 'o')
{
myInfo.setString(1, "xooooooooooooooooooo"); // key change
myInfo.store();
}
}
}
