Trim away from variable in Stored proceedure?

Question

Below i have a Store Procedure with 3 variables that I pull
in. The
@search1 and @search3 are not the problem because they can
hold 100 or
6000 characters. The @search2 gives me a problem because,
when I use the
search form on my page and type more than 20 characters, I
get an error.
Well, that is if I got the error nailed down.
The error I get is "Application uses a value of the wrong
type for the
current operation." Line 192 is the @search2 line.
My question is how would I trim away characters above 20 just
on the
@search2?
Also, do you seen any areas that I could do some "error
catching" in
this SQL ?
Thanks
CREATE PROCEDURE searchresults
@search1 varchar (100),
@search2 varchar (20),
@search3 varchar (6000)
AS
SELECT P.ID AS ProductID, P.Name, P.ProdID, P.Price,
P.ClearSale,
P.SalePrice, P.ShipCost, G.gid, G.pid AS Gpid, G.ord, D.PID
AS DPID,
D.Paragraph, C.Category
FROM atblProducts P
INNER JOIN Groups G ON P.ID = G.pid
INNER JOIN PCat PC ON G.gid = PC.gid
INNER JOIN Categories C ON PC.cid = C.ID
LEFT JOIN Description D ON G.gid = D.PID
WHERE (P.Price IS NOT NULL AND P.Price <> 0 AND
P.Active <> 0 AND PC.ord
= 0 ) AND (P.Name LIKE '%' + @search1 + '%' OR P.ID LIKE '%'
+
@search2 + '%' OR D.Paragraph LIKE '%' + @search3 + '%')
ORDER BY G.gid, G.ord, P.ID, P.Name
GO

You'll have to trim BEFORE it's assigned to a command
parameter's value,
in VBScript: Left(myVariable, 20), if you show line 192 I can
provide the
context where to paste
