How To Sum A Column Depending Of Another Colum Into Different Vars?

Hi all, I am trying to sum a column into different variables depending on another column. Let me explain my self better with an example

DECLARE @Initial decimal(18,2), @incomings decimal(18,2), @outgoings decimal(18,2)

SELECT
@initial = CASE WHEN type = 1 THEN SUM(amount) END,
@incomings = CASE WHEN type = 2 THEN SUM(amount) END,
@outgoings = CASE WHEN type = 3 THEN SUM(amount) END,
FROM Transactions
WHERE date = '05/14/2006' AND STATION = 'apuyinc'
GROUP BY type, amount

What I am trying to do is to sum all of the incomings transactions into @incomings, all of the outgoing transactions into @outgoings and the initial transaction into @initial where
The incoming transactions is type 2,
outgoing transactions is type 3

Thanks for the help
