Gather tag help

Code:

<If Condition="IsTimeBetween(11,13)">
   <TeleportTo Name="Summerford Farms" AetheryteId="52" />
  [B] <Gather While="IsTimeBetween(11,13)">[/B]
      <GatherObject>Mature Tree</GatherObject>
      <HotSpots>
         <HotSpot Radius="100" XYZ="-248.9182, 15.99201, -391.7178" />
      </HotSpots>
      <ItemNames>
         <ItemName>Fire Shard</ItemName>
      </ItemNames>
   </Gather>
</If>		

I'm trying to use <Gather While ="IsTimeBetween(11,13)">

If i start the profile between 11 - 13 this portion works correctly but after 13 i'm still gathering fire shards. is there another while statement i can use to accomplish this?

 

While should be lowercase. Tags and tag parameters are case-sensitive.
