CFSELECT - Binding to two fields?

I've got a simple form with three selects. Make, Model and Year.

Model is bound to Make using:

bind="cfc:getdata.getmodels({make@click})"

bindonload="true"

This works great.

Now, I need to have two fields for makes. I'm trying to do something like this (in my own fake coding words):

<select name="make1" class="input">
           <option value="" selected>Please Select... </option>
           <option value="red">Red</option>
           <option value="Blue">Blue</option>

  </select>

<select name="make2" class="input">
            <option value="" selected>Please Select... </option>
            <option value="white">White</option>
            <option value="black">Black</option>

  </select>

    <cfselect name="model" id="model"
              value="model"
             display="model"
             bind="cfc:getdata.getmodels({make@click}) or ({make2@click})"
                class="input"
                multiple="no"
                bindonload="true"    />

Essentially which ever Make field is chosen is what Model would bind to.I've tried a number of things, even usinig @311770 with no luck. Is this even possible?  I also might have a problem with my CFC:

   <!--- Get model by make name --->
   <cffunction name="getmodels" access="remote" returnType="query">
      <cfargument name="make1" type="string" required="true">
   <cfargument name="make2" type="string" required="true">
      <!--- Define variables --->
      <cfset var data="">
   
     <cfif ARGUMENTS.make1 is not "">
       <!--- Get data --->
      <cfquery name="data" datasource="dsn"   >
      SELECT distinct model
     FROM dataone09
      WHERE make = <cfqueryPARAM value = "#ARGUMENTS.make1#"
   CFSQLType = "CF_SQL_VARCHAR">
      ORDER BY model
      </cfquery>
        </cfif>

      <cfif ARGUMENTS.make2 is not "">
        <!--- Get data --->
       <cfquery name="data" datasource="dsn"   >
       SELECT distinct model
      FROM datatwo09
       WHERE make = <cfqueryPARAM value = "#ARGUMENTS.make2#"
    CFSQLType = "CF_SQL_VARCHAR">
       ORDER BY model
       </cfquery>
         </cfif>

      <!--- And return it --->
      <cfreturn data>
   </cffunction>

Any words of wisdom or guidance would be most helpful,

Thanks!
