hi.I have this page to select and insert form fields:

<CFLOOP list="#form.fieldNames#" index="x">
<CFSTOREDPROC procedure="sp_Eman_AddSupplements" dataSource="#session.eManager.datasource#">
<CFPROCPARAM type="IN" CFSQLType="CF_SQL_VARCHAR" value="#form.supplementIng#" dbVarName="@supplementIng">
<CFPROCPARAM type="IN" CFSQLType="CF_SQL_VARCHAR" value="#form.supplementAmount#" dbVarName="@supplementAmount">

CREATE PROCEDURE sp_Eman_AddSupplements
@supplementIng varchar(250),
@supplementAmount varchar(15),
@supplementDaily varchar(15),
@10919279 int
AS
SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED
SET LOCK_TIMEOUT 4000
SET NOCOUNT ON

SELECT TOP 1 product_id
FROM tbl_product_supplement
WHERE product_id = @10919279 AND
supplement_ingredient = @supplementIng AND
supplement_amount = @supplementAmount AND
supplement_daily =@supplementDaily

IF (@@ROWCOUNT = 0)
BEGIN
INSERT INTO tbl_product_supplement
