Report Expression help needed

I have a Dataset which has 3 columns " Count" gives me a number, " Warehouse" has a name of Warehouse like North,South,East,West and " Status" with In or Out values.

Currently  shows 10 Trucks are IN, for a particular location, which is all of the Trucks in Tennesse, could it also say 0 Trucks are OUT,

Can someone help me with the expression?

      Trucks
------------------
In              10
Out		0
What i need to add is if "10" trucks are out which are total trucks for that warehouse i
i need to add "Out" as 0
