3 related selects using javascript and CF

[Shelgas]

I'm ready to tear my hair out! Can anybody find why the data in the third dropdown list is not correct? When I dump it, everything is correct. But in the dropdown, it's all wrong.

<cfquery  name="getAuto" datasource="thisSource">
	SELECT TFAutoMake.ID, TFAutoMake.Make, TFAutoModel.MakeID, TFAutoModel.Model, TFAutoModel.ModelID
	FROM TFAutoMake, TFAutoModel
	WHERE TFAutoMake.ID = TFAutoModel.MakeID
	ORDER BY TFAutoMake.Make, TFAutoModel.Model
</cfquery>

<cfquery name="getModelYear" datasource="thisSource">
	SELECT 		TFAutoModel.Model, TFAutoModel.ModelID, TFAutoModelYear.YearID, TFAutoModelYear.ModelYear
	FROM		TFAutoModel, TFAutoModelYear
	WHERE		TFAutoModel.ModelID = TFAutoModelYear.YearID
	ORDER BY	TFAutoModel.Model, TFAutoModelYear.ModelYear
</cfquery>


    <cfset idx = -1>
    <cfset myauto = 0>
    <!--- send the selected make to determine the model list to display   ---> 
    <script language="JavaScript1.2">
        function whichAuto(obj){
			switch (obj.selectMake.selectedIndex){
			<!--- use the group attribute to group output by category --->
			<cfoutput query="getAuto" group="Make">
			<cfset myauto = myauto + 1>case #myauto#:
				<cfset autoList = ValueList(getAuto.ID)>
				<cfset numberInMake = ListValueCount(autoList, MakeID)> 
					 obj.selectModel.length=#numberInMake#<cfoutput><cfset idx = idx + 1>
					 obj.selectModel.options[#idx#].value="#getAuto.MakeID#"
					 obj.selectModel.options[#idx#].text="#getAuto.Model#"</cfoutput> 
					 break;
				<cfset idx = -1>
			</cfoutput> 
			} 
       }
    </script>

    <cfset idx = -1>
    <cfset myYear = -1>
    <!--- send the selected make to determine the model list to display    ---> 
    <script language="JavaScript1.2">
        function whichYear(obj){
			switch (obj.selectModel.selectedIndex){
			<!--- use the group attribute to group output by category --->
			<cfoutput query="getModelYear" group="Model">
				<cfset myYear = myYear + 1>case #myYear#:
				<cfset yearList = ValueList(getModelYear.ModelID)>
				<cfset numberInModel = ListValueCount(yearList, YearID)> 
					 obj.selectYear.length=#numberInModel#<cfoutput><cfset idx = idx + 1>
					 obj.selectYear.options[#idx#].value="#getModelYear.ModelID#"
					 obj.selectYear.options[#idx#].text="#getModelYear.ModelYear#"</cfoutput> 
					 break;
				<cfset idx = -1>
			</cfoutput> 
			} 
       }

    </script>
