Vouchers for range of categories and products

[EMurph]

Hi,

i want to set up a discount voucher for a group of customers.

These customers get a discount from all books (which is one category) and certain specificied training courses.

I have successfully set up the discount for the category,  but when I try to add the training courses, it stops working,

 

It is acting as though the discount is applied only if the cart contains a product which is in a category AND a specific product,

but I want to the discount to apply if they buy a book OR  a specific training course.

 

Is this possible and if someone can someone hep me set it up,

 

Thanks,
