How to use CFPARAM with list of string values

Hi All,

I have a field value that can be stored with many values for a single record: Work_Order = '555555,666666,111111' (note, these are actually stored as a single string value in the db with commas .)

I need to parse this field and enter the string values into the where clause of a new query:

<CFSET WOIDS = CapProjects.Work_Order>

<cfloop condition="#find(',,',WOIDS)#">

<cfset WOIDS = "#rereplace(WOIDS,',,',',null,','ALL')#"><br>

</cfloop>

  <cfquery name="CapProjectsWOIDS" datasource="#URL.DB#">
  SELECT [ENGOPSMTRLSID]
      ,[Work_Order]
  FROM ENGOPSMTRLS
  WHERE
<CFOUTPUT>
  ENGOPSMTRLSID = #URL.INDEX#
</CFOUTPUT>
AND
<CFOUTPUT>
  Work_Order in  (<cfloop index="idx" list="#variables.WOIDS#">
        <cfqueryparam
                        value=#WOIDS#
                        cfsqltype="cf_sql_varchar"
                         list="true"
                         /></cfloop>)
</CFOUTPUT>
</cfquery>

Am I doing this right? I'm getting the following error: Error Executing Database Query. [Macromedia][SQLServer JDBC Driver][SQLServer]Incorrect syntax near '@P4'. Is that the loop length? How do I pass that in?

Thanks,

John
