In this xslt I am try to get the count of how many th I am making. Because I need to know how many <input type="radio"></input> I need to make. I created this variable set But it looks like it is out of scope? is there any other way to do this?

 <xsl:for-each select="MeetingPollingParts/MeetingPollingParts">
   <table class="table" style="width:100%;border-color:gray">
   <xsl:choose>
       <xsl:when test="MeetingPollingPartsTypeId = 3">
           <thead>
             <tr>
               <xsl:for-each select="MeetingPollingPartsValues/MeetingPollingPartsValues">
                 <xsl:variable name="set" select="MeetingPollingPartsValues/MeetingPollingPartsValues" />
               
                 <th>
                   <xsl:value-of select="QuestionValue" disable-output-escaping="yes"/>
                 </th>
               </xsl:for-each>
             </tr>
           </thead>
       </xsl:when>
       <xsl:when test="MeetingPollingPartsTypeId = 5">
         <tbody>
               <xsl:for-each select="MeetingPollingPartsValues/MeetingPollingPartsValues">
                 <tr>
                   <td style="padding: 8px;line-height: 1.42857143;vertical-align: top;border-top: 1px solid #ddd;">
                     <xsl:value-of select="QuestionValue" disable-output-escaping="yes"/>
                   </td>
                   <td style="padding: 8px;line-height: 1.42857143;vertical-align: top;border-top: 1px solid #ddd;">
                     <input type="radio"></input>
                   </td>
                 </tr>
               </xsl:for-each>
           </tbody>
       </xsl:when>
   </xsl:choose>
   </table>
 </xsl:for-each>
