When I view source of your page, I do not see the script that should be created by the Create Dynamic Array behavior. the dynamic array for the child list is not being created.
This suggests that the there is either an error on the page, or the SQL for the recorsdset is not returning any results.
hre are a few things to try for troubleshooting:
1: add the following at line 1:
2 add this code after the body tag:
echo("Today is: ".date()."<br />");
echo("rsSub Total Rows: ".$totalRows_rsSub);
this will write any php errors to the screen and tell us how many rows are being returned by the recordset that is used for the dynamic array.
