Unmatched Records for Specific Product ID Query

Experts,

I am at a total loss! I cannot figure out the correct syntax for a query that is trying to find unmatched records.

I have the following tables:

tblProductPrice
PK: CostID
Lng: SiteID
Lng: TTechID


tblWebsite
PK: WebsiteID
Str: WebAddress

The query will have a particular TTechID that it needs to find any WebsiteID's that are not in the tblProductPrice.SiteID for that specific TTechID.

I've tried the following sql
SELECT tblWebsite.WebAddress
FROM tblWebsite
WHERE NOT EXISTS (SELECT SiteID FROM tblProductPrice WHERE tblProductPrice.SiteID = tblWebsite.WebsiteID)

Open in new window


and

 
SELECT tblWebsite.WebAddress
FROM tblWebsite LEFT JOIN tblProductPrice ON tblWebsite.WebsiteID = tblProductPrice.SiteID
WHERE (((tblProductPrice.SiteID) Is Null));

Open in new window


Neither of these work correctly specifically because they don't have any reference to the TTechID in question.

Please help me add whatever conditional statement is needed to refine the query search to the specific TTechID in question.

Thank you!

Please find the query below
DECLARE @TTechID INT
SET @TTechID =1
SELECT
