  27 =head1 DESCRIPTION
  28
  29 This script checks the amount unallocated from the new parent budget , or the period - if no parent_id is given
  30
  31 This script is called from aqbudgets.pl during an 'add' or 'mod' budget, from the JSscript Check() function,
  32 to determine whether the new parent budget (or period) has enough unallocated funds for the save to complete.
