Quote template, Add Unit Name from Price List

Hi Everyone,

I am creating a Word template for a quote using the XML mappings feature in Word. What is the xml mapping field for the price list unit in the word template? For example in the quote we have a product description called "temp work" the unit in the price list is "hour" and the price is "$25".  We are able to map the description, and the price but not the unit. What is the field for "unit". Your help is greatly appreciated. Thank you!
