Create a marco to assign numbers

[Val Leonard]

I have created a template for a purchase order. I would
like to create a marco that will assign the Purchase
Order number automatically whenever the used goes to
create a new purchase order using the next available
number. Does anyone know what steps are needed to create
this macro. Anything I have tryed doesnt' work. I can
create the button on the toolbar for the macro, but don't
know how to create the marco.

Thanks

range("a5")=range("a5")+1
