Yes, that's definitely possible! Here's an example GlideRecord query that should achieve that:

```

var taskGr = new GlideRecord('sc_task');

taskGr.addQuery('assignment_group', 'your_group_name_here');

taskGr.query();

var reqItemGr = new GlideRecord('sc_req_item');

var reqItemIds = [];

while (taskGr.next()) {

reqItemGr.addQuery('request', taskGr.getValue('request'));

}

reqItemGr.addQuery('stage', 'requested');

reqItemGr.query();

while (reqItemGr.next()) {

reqItemIds.push(reqItemGr.getValue('sys_id'));

}

var totalPriceGr = new GlideAggregate('sc_req_item');

totalPriceGr.addAggregate('SUM', 'total_price');

totalPriceGr.addQuery('sys_id', 'IN', reqItemIds);

totalPriceGr.query();

if (totalPriceGr.next()) {

var totalPrice = totalPriceGr.getAggregate('SUM', 'total_price');

gs.print('Total price: ' + totalPrice);

}

```

This query first queries the sc_task table to find all tasks assigned to your group, and then uses the request field to query the sc_req_item table to find all RITMs associated with those tasks. It then uses GlideAggregate to perform an aggregate function (SUM) on the total_price field of the sc_req_item records that meet the specified conditions. Let me know if you have any questions or if this helps!
