In addition to missing braces in the if-statement, you have a problem with this line:
<c>
my($num1,$flag)=shift;
</c>
<tt>shift</tt> only returns one element from @_. You probably mean:
<c>
my($num1,$flag)=@_;
</c>
<!-- Node text goes above. Div tags should contain sig only -->
<div class="pmsig"><div class="pmsig-137386">

</div></div>
