[dba-SQLServer] Stored Procedure Help (SQL Server & VB6)

To all,
 
I have a Visual Basic 6 front-end together with a SQL Server 7.0 back-end, and have tried writing a stored procedure to do the following:
 
I pass a UserID into the SP, then I want the SP to UPDATE tblPersonnelJobCategories to TRUE where tblPersonnelJobCategories.UserID is equal to the UserID that I passed to the SP but I only want the UPDATE to take place where the PayrollNo & CategoryID in tblPersonnelJobCategories matches the PayrollNo & CategoryID in tblPersonnelCategoriesSelected
 
I tried using the follwing SQL statement in my SP but it doesn’t like the Inner Join:
 
UPDATE tblPersonnelJobCategories INNER JOIN tblPersonnelCategoriesSelected ON (tblPersonnelJobCategories.CategoryID = tblPersonnelCategoriesSelected.CategoryID) AND (tblPersonnelJobCategories.PayrollNo = tblPersonnelCategoriesSelected.PayrollNo)                   SET tblPersonnelJobCategories.Selected = True  WHERE tblPersonnelJobCategories.UserID= @UserId
 
Any help would be greatly appreciated, as I’m fairly new to SP’s and thought an INNER JOIN would be ok.
 
Thanks in advance for any help
