How can I generate a view that will give a SUM of specific columns from multiple other views?

Good morning, Experts-Exchange community.  

I currently have 8 SQL views that give some detailed calculations based on a Customer ID which in turn will be used to generate a scoring model.  Is there a way for me to create another view that will show all Customer ID's, all 8 results, and a SUM?

Here's the kicker.  One view holds a DISTINCT listing of every Customer ID in the database along side it's Customer Type with a score given to the type.  Other views do not show every Customer ID as they may not receive a score due to not meeting the criteria.

Examples:

View 1:
CustID  |  CustType  |  TypeScore
1234  |  O  |   5
5678  |  B   |   15
6543  |  O  |   5
3456  |  B  |   15

View 2:
CustID   |   CustState   |   StateScore
1234  |  OH  |   0
5678  |  CA   |  20
6543  |  MI    |   20
3456  |  OH  |   0

View 3:
CustID   |   CashCount   |   CountScore
1234   |    6    |    30
6543   |    2    |    15

(The view I would want to create w/ the three "Score" columns with any and all Distinct Customer ID's - from "View 3", the customer ID's that aren't there would get a default value of "0"...)
SUM View:
CustID   |   TypeScore  |   StateScore   |   CountScore   |    ScoreSUM
1234   |   5     |   0    |   20  |   25
5678   |   15   |   20  |   0    |   35
6543   |   5     |   20  |   15  |   40
3456   |   15   |   0    |   0    |   15

Is something like this possible???

Better yet.  Would it be more wise to combine all 8 views into one?  I can post the Queries used in each view if this helps.

this will do

SELECT
	View1.* ,
	IsNull(View2.StateScore, 0) StateScore,
	IsNull(View3.CountScore, 0) CountScore,
	View1.TypeScore + IsNull(View2.StateScore, 0) + IsNull(View3.CountScore, 0) ScoreSUM
FROM
	View1
	LEFT OUTER JOIN View2 ON View1.CustID = View2.CustID
	LEFT OUTER JOIN View3 ON View1.CustID = View3.CustID

Open in new window


if all View get data from same table.
create SUM view directly from code maybe better.

Thank you JoeNuvo!
The code you provided worked wonders.  Combining all views into one is going to have to wait until I open up more programming time.  This will help me greatly in the meantime.
