I am writing a report to show some purchasing data.

There are a few instances where we purchase services as well as good from a vendor.  When we create this type of purchase order there are two lines to distinguish a purchase of goods and a purchase for services.  In my database these are considered a purchase type of 1 and 2 respectively. 

I am looking for a way that will limit my report to only show me purchase orders that contain both a purchase type of and and 2 and show me both lines on that purchase order. 

is that clear as mud? 

Thank you. 

I also need to add one more criteria to this.  If I wanted to limit to particular type of service.... lets say office cleaning (which has a key of 4 in my DB) how would i encompass this to the with the above formula and still achieve the same result of showing both lines of the purchase order? 

Awesome. 

thank so much for the help
