cfselect selected= not working properly

I have an update page with a cfselect populated from a query.  I need the selected value to be = to a value from a different query.

I can only seem to get the first item in the cfselect to display when the page loads, making me think something is wrong w/my cfselect.

This tag, btw, is w/in a <cfoutput> tag from the other query.

ex:

<cfquery name="QUERY1">
SELECT tblMain.Name as name, tblMain.Other_Name, tblMain.TrussTypeID

FROM tblMain

</cfquery>

<!-- get list of all truss types -->

<cfquery2 name="QUERY2>

SELECT lkuTruss.TrussTypeID, lkuTruss.TrussType
FROM lkuTruss
ORDER BY lkuTruss.TrussType
</cfquery>

<cfoutput query="QUERY1">

<table>.....etc.

<td>

<!--populate select box w/all possible truss types.  Have matching truss type for selected record pre-displayed-->

<cfselect name="i_p_select" query="QUERY2" value="TrussTypeID"  display="TrussType" selected="#QUERY1.TrussTypeID#" />

etc etc...

</table>

</cfoutput>

I've seen other examples similar but mine won't work!
