cfargument Question

[RosieGp]

I have a combobox and textinput where the user makes a selection from the combobox and then put text in textinput box to retrieve information... Now in cfc
I have the following:

<cfcomponent  output="false">
<cffunction name="getData" access="remote" returnType="query" output="false">
<cfarument name="TextUserInput" required="true"/>
<cfset var DataQRY ="">
<cfquery datasource="SQL" username="***" password="***" name="SQLQuery">
       select EmpID, EmpName
       from   Employee
[COLOR=red]       where  TextUserInput IN (#ListQualify('#TextUserInput#')#) [/color red]
</cfquery> 
<cfquery datasource="oracle" username="***" password="***" name="OracleQuery">
       select emp_NUM, emp_DATE
       from   emp_INFO  
[COLOR=red]       where  TextUserInput IN (#ListQualify('#TextUserInput#')#)[/color red] 
</cfquery>
<cfquery dbtype="query" name="DataQRY">
       select SQLQuery.EmpID, SQLQuery.EmpName, OracleQuery.emp_DATE
       from SQLQuery, OracleQuery 
       Where SQLQuery.EmpID=OracleQuery.emp_NUM
</cfquery>
        <cfreturn DataQRY>
        </cffunction>
</cfcomponent>

I don't know if this is correct way of getting the argument...
my flex end looks like the following:
