Sort a report inserted in an exact form after being grouped.

I have a report inserted in an exact form which is grouped by the field [index][11]. But once it is grouped, I need it sorted by the date [filed][13]. The grouping works [11], but the subsequent sort of the grouped items [13] does not. Help!

~=qdb.GetURL("bmm6tc3xp",
"API_GenResultsTable^query={'14'.EX.'"+ field["Record
ID#"]+"'}^clist=7.8.9.13.10^options=nvw.ned.phd.nfg.sortorder-A.groupby-V^slist=11.sortorder-A^slist=13^ts="+
new Date().getTime());~
