<?xdoxslt:set_variable(
$_XDOCTX,
'RTotVar',
xdoxslt:get_variable($_XDOCTX, 'RTotVar') + ACCTD_AMT)
?>
<?xdoxslt:get_variable($_XDOCTX, 'RTotVar')?>

3. Display value set using get_variable

<?xdoxslt:set_variable($_XDOCTX, 'currentrowdr_share_value', 0)?>
<?if:ACCOUNTED_DR!=''?>
  <?xdoxslt:set_variable($_XDOCTX, 'currentrowdr_share_value', ACCOUNTED_DR)?>
  <?xdoxslt:get_variable($_XDOCTX, 'currentrowdr_share_value')?>
