Custom navigation dropdown menu /To null out a collection or variable in 6.

Question

Is there are way to clear a variable or Null out a Collection in 6.5.We are having problem with displaying pages of a communities in navigation menu.Since the pages for a community is fetched inside the loop, the pages in each community gets appended to the data variable "subpages". I want a way to empty the elements in "subpages", just before getting the pages for the next community in the loop.
code-->
<pt:ptdata.mycommunitiesdata pt:id="commLinks" />
<pt:logic.sort pt:data="commLinks" pt:sorteddata="sortedComms" />
<pt:logic.foreach pt:data="sortedComms" pt:var="link">
<pt:core.html pt:tag="a" href="$link.url" ><pt:logic.value pt:value="$link.title"/></pt:core.html>
<pt:ptdata.communitypagesdata pt:id="subpages" pt:commid="$link.objid" />
<pt:logic.foreach pt:data="subpages" pt:var="sp">
<pt:core.html pt:tag="a" href="$sp.url"><pt:logic.value pt:value="$sp.title"/></pt:core.html>
</pt:logic.foreach>
</pt:logic.foreach>
Any ideas??

Answer 1

I scratched my head a whole lot on this one too. Try doing this. Just before you initialize your subpage variable:
<pt:logic.collection pt:key="subpage"/>
Adding that line seems to do the trick.
