Exporting dynamic query to Excel

I'm trying to query a database and write the results to an Excel spreadsheet.

The page seems to be compiling correctly and I've tested the table outputting to a .cfm page which works fine.
However as soon as I try and write to an Excel file I lose my table in to thin air (ie no output, a blank spreadsheet).
Here's my code:

<cfquery name="getReportDetails" datasource="myDataSourceName">
SELECT t1.RedemptionID, t2.Model, t2.AwardName, t1.Qty, SUM((t2.cost * t1.Qty) + t2.Est_Delivery) AS cost
FROM tblo_memberorders t1,
tblp_Awards t2
WHERE t1.AwardID = t2.AwardID
AND t1.Status = 1
AND t2.SupplierID = #Form.Supplier#
GROUP BY t1.RedemptionID, t2.Model, t2.AwardName, t1.Qty, cost
</cfquery>
<cfset totalCost = 0>

<!--- write the column headers --->
<cffile action="WRITE" file="orderForm.xls" output="
<cfcontent type='application/ms-excel'>

<table>
<tr>
<td><strong>RepemtionID</strong></td>
<td><strong>Model No</strong></td>
<td><strong>Product Name</strong></td>
<td><strong>Contact Name</strong></td>
<td><strong>Business Name</strong></td>
<td><strong>Address</strong></td>
<td><strong>Suburb</strong></td>
<td><strong>State</strong></td>
<td><strong>Postcode</strong></td>
<td><strong>Phone</strong></td>
<td><strong>Qty</strong></td>
<td><strong>Cost</strong></td>
</tr>" addnewline="Yes">

<!--- append the other data to the table --->
<cfloop query="getReportDetails">
<cffile action="APPEND" file="orderForm.xls" output="
<tr>
<td><cfoutput>#getReportDetails.RedemptionID#</cfoutput></td>
<td><cfoutput>#getReportDetails.Model#</cfoutput></td>
<td><cfoutput>#getReportDetails.AwardName#</cfoutput></td>
<td>Justine</td>
<td>CiEvents</td>
<td>115b Ferrars Street</td>
<td>South Melbourne</td>
<td>Victoria</td>
<td>3205</td>
<td>(03) 86967013</td>
<td><cfoutput>#getReportDetails.Qty#</cfoutput></td>
<td>$<cfoutput>#getReportDetails.cost#</cfoutput>
<cfset totalCost = totalCost + getReportDetails.cost></td>
</tr>" addnewline="Yes">
</cfloop>

<!--- end table in the file --->
<cffile action="APPEND" file="orderForm.xls" output="
<tr>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
<td><strong>Total Cost:</strong></td>
<td><strong>$<cfoutput>#totalCost#</cfoutput></strong></td>
</tr>
</table>" addnewline="Yes">
