How to calculate counts from different dates into 1 date

Question

Hi,
I have a scenario below
ID
Type
Country
Date
123AP1
P
US
1/1/2009
123A1
A
WO
4/4/2010
123A2
A
US
6/6/2011
123A3
A
US
8/8/2011
So, the logic I need to display is -
If, Type = P AND Country=US then count 1 where ID has 123AP1
else If Type = A AND Country=US then count 1 more where ID has 123AP1 on date 1/1/2009 (i.e. on Type P date)
So, result should show
ID
Type
Country
Date
Count
123AP1
P
US
1/1/2009
3
123A1
A
WO
4/4/2010
0
123A2
A
US
6/6/2011
123A3
A
US
8/8/2011

Please simplify the question while asking to make it easy to understand.. this question is very confusing to understand..
For your purpose you should be able to get the result using calculation context based count on a  conditional variable with all your logic
Create a variable like below
var =if  [Type] = 'P' [ID] = '123AP1' and [Country] = 'US' then 1 else if Type] = 'A' [ID] = '123A1' and [Country] <> 'US'  thenn 1
And then create a formula on this variable like below
Count = sum([Var]) forall [Date]
