Passing values with a hidden CFInput
===

I am trying to make a table with editing capabilities, and I have run into problems trying to associate the old values with the updated ones. My solution was to include a hidden CFInput that passes the old value along side the one to be updated, and then the query is run within a cfc.

    <cfform name="update" method="post">
	<cfoutput query="allusers">
		<tr>
			<td>#username#</td>
			<td>#email#</td>
			<td>#securityID#</td>
			<td><a href="">DELETE</a></td>
		</tr>
			<td><cfinput name="oldUsername" value="#username#" type="hidden"></cfinput><cfinput name="updateUsername" value="New Value"></cfinput></td>
			<td><cfinput name="oldEmail" value="#email#" type="hidden"></cfinput><cfinput name="updateEmail" value="New Value"></cfinput></td>
			<td><cfinput name="oldSecurityID" value="#securityID#" type="hidden"></cfinput><cfinput name="updateSecurityID" value="New Value"></cfinput></td>
			<td><cfinput name="submit" type="submit"></cfinput>
		<tr>
			<cfdump var="oldUsername">
	</cfoutput>
</cfform>

Currently I am not getting any errors, but it does not seem to be passing in the old values. Any tips?
