Get Item Quantity using QSRules

I am writing an add-in and I want to get the Quantity in stock for an item. I can add an item to the transcation and do the following to get the lookup code.

Entry.Item.ItemLookupCode

Is there a way to get the quantity of the Item. I don't mind if I have to add it to the transaction first or not to get this info, I just want to be able to disaply the stock value.

Is this possible?

Thanks Debra
