Hi David,

You Did everything Correct except the way you are accessing the public 
variable. For Accessing the public variable from Another work book you need 
to add the reference of that work book into your current work book
then only you can use that variable in your current work book. For more 
explaination you can go through the following link this link will guid you 
how can you access the public variable.
