Use # sign to reference your spotSchedule variable inside <s:iterator> tag.

<s:set var="totalSpots" value="0"/>
  <s:iterator var="spotSchedule" value="spotSchedules">
    <s:set var="totalSpots" value="#totalSpots + #spotSchedule.noOfSpots" />
  </s:iterator>
<span style='cursor:pointer;text-decoration:underline;padding-left:5px;color:blue;'>
   <s:property value="#totalSpots"/>
</span>
