Any SQL Gods Out There????

I have a SP that I am trying to finalize however; my inexperience is showing itself on this one.

History:
3 Tables: Tooldb - Employee - ToolUserdb

Scenario:
I have a webform in c# that gathers data concerning internal tools(applications) that are written in-house. One of the fields is a listbox of names pulled from the Employee table called Creator. When the form is submitted I need to have the list of selected employees published to the ToolUserdb.

My SP:
ALTER PROCEDURE dbo.InsertTool
(
@ToolNamenvarchar(250),
@Platformnvarchar(250),
@Vendornvarchar(250),
@Subplatformnvarchar(250),
@Submitternvarchar(250),
@Finders nvarchar(250),
@LTDnvarchar(50),
@JobAreanvarchar(250),
@Funcnvarchar(250),
@Ownersnvarchar(250),
@Activenvarchar(250),
@Version numeric,
@Buildnumeric,
@CWSTDnvarchar(50),
@Statusnvarchar(250),
@Costnumeric,
@Notesnvarchar(250),
@Keywordsnvarchar(250),
@Linksnvarchar(250),
@Pathsnvarchar(250),
@eidint,
@tdbidint,
@Creator nvarchar(250)
)
AS

INSERT INTO [ToolDB] (ToolName, Platform, Vendor, Subplatform, Submitter, Finders, LTD, JobArea, Func, Owners, Active, Version, Build, CWSTD, Status, Cost, Notes, Keywords, Links, Paths)
VALUES
(@ToolName, @Platform, @Vendor, @Subplatform, @Submitter, @Finders, @LTD, @JobArea, @Func, @Owners, @Active, @Version, @Build, @CWSTD, @Status, @Cost, @Notes, @Keywords, @Links, @Paths)
INSERT INTO ToolUsersdb (@Creator) SELECT + @eid + ',[ID] FROM Employee + @tdbid + ',[ID] FROM ToolDB IN (@Creator)

Error:
Incorrect syntax near keywork IN (referring to last insert statement).

Can someone tell me how I can get this multi-insert stmt. to work?

Thank you!
