Using cftree

I load the tree with an cfquery and i display the Agent name and the AgentNo as the value.

Here is the code
_________________________________________________
<cfif "#session.masteragentno#" eq "478928535" or "#session.masteragentno#" eq "507806807" or "#session.masteragentno#" eq "360646731">
<cfquery name="getAgentsView" datasource="AgentSys">
SELECT [First Name] + N' ' + [Last Name] AS Name, AgentNo As agent
FROM tblAgentMaster
WHERE ([Group] LIKE N'%Headrick%')
ORDER BY [First Name] + N' ' + [Last Name]
</cfquery>
<cfelseif "#session.masteragentno#" neq "">
<cfquery name="getAgentsView" datasource="AgentSys">
SELECT tblAgentMaster.[First Name] + N' ' + tblAgentMaster.[Last Name] AS Name, tblAgentMaster.AgentNo As agent
FROM tblHierarchyColumns INNER JOIN
tblAgentMaster ON tblHierarchyColumns.ColumnID = tblAgentMaster.HierarchyColumn
WHERE (tblAgentMaster.TeamLeader = N'#session.masteragentno#')
ORDER BY tblAgentMaster.[First Name] + N' ' + tblAgentMaster.[Last Name]
</cfquery>
</cfif>
<cfformgroup type="HBox">
<cfformgroup type="VBox">
<cfif getAgentsView.Name neq "">
<cftree
