custom tags

Hi

I am new to CF and I am creating a custom tag with two attributes. However when calling the custom tag with name as "datefrom" and date as 01/01/2008, the calling page came with this error: "Variable DATEFROM is undefined".

In my custom tag:
<cfparam name="Attributes.date">
<cfparam name="Attributes.name">

<cfset dateA = "#Attributes.date#">

<cfset dateB = "#mid(dateA,7,4)&'-'&mid(dateA,4,2)&'-'&mid(dateA,1,2)#">
<cfset #Attributes.name# = "#dateB#">


Calling page:
<cf_convertdatetoSQL date="url.fromdate" name="datefrom">
<cf_convertdatetoSQL date="url.todate" name="dateto">
<cfquery name="balancesheet" datasource=#url.code#>


SELECT AccountCategories.accountcategoryname, sum(Transactions.debit) AS Total,dbo.accountcategories.acctype
FROM dbo.AccountCategories, dbo.AccountNumbers, dbo.Transactions
WHERE dbo.AccountCategories.accountcategoryno = dbo.AccountNumbers.accountcategoryno
AND dbo.AccountNumbers.accountno = dbo.Transactions.accountno
AND dbo.Transactions.date BETWEEN '#datefrom#' AND '#dateto#'
GROUP BY dbo.accountcategories.accountcategoryname,dbo.accountcategories.acctype

ORDER BY CHARINDEX(dbo.accountcategories.acctype, 'Asset,Liability,Equity') ASC

</cfquery>
etc..

Can anyone please let me know what I am doing wrong?

Thanks
