评估函数返回＆＃34; undefined＆＃34;值

Question

以下代码在一个浏览器（IE 11）中返回值，但在不同服务器的浏览器（IE 11）中，它会抛出错误＆＃34; checkRatingId未定义＆＃34;。

<cfloop index="FieldName" list="#fieldNames#">
    <cfset field_name = #FieldName#>
    <cfset firstThreeChars = #Mid(field_name,1,3)#>

        <cfif firstThreeChars eq "CQI">
        <cfset checkQuestionId = #RemoveChars(field_name,1,3)#>

        <cfset checkRatingId = #Evaluate("#field_name#")#>

        <cfquery name="InsQuestions" datasource="#variables.dbdsn#" username="#variables.dbuser#" password="#variables.dbpw#">
            insert into quality.employee_quality_call_detail
            (quality_call_detail_id, check_question_id, check_rating_id, quality_call_id,
             last_user, last_update)
            values
            (quality.seq_emp_quality_call_detail.nextval, '#checkQuestionId#','#checkRatingId#',
             '#qualityCallId#', '#currentHRID#',sysdate) 
        </cfquery>

    </cfif>
</cfloop>
