Error converting data type varchar to float.

Hi,
I am receiving this error when trying to pass a value from ASP to SQL,
below is the SP and a snippet from the update code from the ASP page,
any ideas on how to rectifiy this. I have used a similar syntax in an
add SP and that works fine, the supp_rent_val2 and usr_rent_val2 are the
two values im passing in:
======SP======== CREATE PROCEDURE dbo.cnms_rentals_update
@.RENT_TYPE_SUPP FLOAT= NULL,
@.RENTAL_SUPP VARCHAR(1)=NULL,
@.RENT_TYPE VARCHAR(1)= NULL,
@.RENTAL FLOAT= NULL,
@.START_DATE DATETIME= NULL,
@.END_DATE DATETIME = NULL,
@.ROW_ID INT= NULL
AS
BEGIN
UPDATE RENTAL SET
RENT_TYPE_SUPP = convert(float,@.RENT_TYPE_SUPP),
RENTAL_SUPP = @.RENTAL_SUPP,
RENT_TYPE = @.RENT_TYPE,
RENTAL = convert(float,@.RENTAL),
START_DATE= @.START_DATE,
END_DATE = @.END_DATE
WHERE
row_id = @.ROW_ID
END
GO
==========ASP========= szSQL="EXEC dbo.cnms_rentals_update"
if request("supp_rent_val2")<> "" then
szSQL = szSQL & ", @.RENT_TYPE_SUPP = " & request("supp_rent_val2")
end if
if request("supp_rent_per2")<> "" then
szSQL = szSQL & ", @.RENTAL_SUPP = '" & request("supp_rent_per2")& "'"
end if
if request("usr_rent_val2")<> "" then
szSQL = szSQL & ", @.RENTAL = " & request("usr_rent_val2")
end if
===================================
Thanks in advance
Peter

Don't just participate in USENET...get rewarded for it!You didn't include the error. But, beyond that why are you using float?
Not that it might not be appropriate, but as an approximate data type I
would have a hard time recommending its use when it comes to monetary
transactions.
