Well that error means that you already have an object for that reference number. Since your loop is from 1 to 50, if you have an object of any number between 1 and 50, this part of the program will crash. What I like to do when I need an object number is use a function like this to return the next free object number:



So if you used the function above, you could modify your current code to look like this:



Then you'll be sure that the objects you create will use an object number that hasn't been taken up already.

Hope that helped!

Although in your code position object would go to the next free object that doesn't exist so it would still crash. Just make a temp variable like this:
