How Do Make Sure If Column Is Null Before I Count It? ( Use SQL 2000)

 the Table columns is like this
 
NO          ProductNo              Area            In               Out
1               0001                     US             NULL          NULL
2               0002                     UK             NULL          Y
3               0003                     FR              Y                NULL 
4               0004                     FR              Y                NULL
5               0005                     UK              Y                NULL
 
I have Query get the result below
Area       Count         In&Out
US           1

UK           2

FR           2
 
the Area is Group By by Area
and the Count columns is counting how many recoreds Table for each Area
the problem is the column "In & OUt'
I have to make sure if the "In" or "Out" is  Null , if one of them is  Null the plus 1
 
so the result would like
 
 
I have Query get the result below
Area       Count         In&Out
US           1                 1


UK           2                 1


FR           2                  0
 
which syntax I can use for the problem? I just think maybe I can use IsNULL?
but I have no idea how to wirte a query ...
can you give me a hint? thank you
