reuse select query result

Hi,

I have a SQL select query, it works fine as it is now.

Code:

---

select namee as 'FULL NAME',
sum(inn)  as 'Money', sum(case when color='red' or color='MEDIUM red' or color = 'LIGHT red' then isnull(out,0) else 0      End) as 'FIRST RESULT',
sum(case when color='red' or color='MEDIUM LIGHT red' then isnull(inn,0) - isnull(out,0) else 0      End) as 'SECOND RESULT'
from yyyyyyyy where  ID = 100 group by namee

---

But I would like to be able to get the result of each case ex: final result of "FIRST RESULT" and "SECOND RESULT" and to be able to reuse it in my next line of code like

Code:

---

sum(case when color='red' or color='MEDIUM LIGHT red' then isnull(inn,0) - isnull('FIRST RESULT',0) else 0      End) as 'THIRD RESULT'

---

I'm not sure how i can accomplish that, any tip will be appreciated.

Thanks
