In change request, how do i calculate both risk and impact using only risk assessment?

[MukeshP203]

The risk assessment includes the following two additional fields:

Could this cause a severe outage? (Yes/No)

-If marked as Yes, the CR is marked as "High Risk".

-If marked as No, the risk assessment runs with the standard OOTB functionality.

What is the business criticality of this CR/Item?

-If the criticality is High, the Impact is marked as High.

-If the criticality is Low, the Impact is marked as Low.

I am trying to take an approach where i am using risk conditions advanced script to tap into the answers of the risk assessment questions and then set the Impact. Here is the incomplete background script i am trying to get that particular assessment instance, created when the risk assessment form is answered, linked with the Change Request.

var mat = new GlideRecord('asmt_metric_type');

    mat.get('415f1e131bde56106cb85204604bcba7');

    mat.query();

    if(mat.next()){

        gs.print(mat.name);

    }

    var changeRecord = new GlideRecord('change_request');

// changeRecord.orderByDesc('sys_created_on');

changeRecord.query();

if(changeRecord.next()){

var changeSysId = changeRecord.sys_id;

changeRecord.get(changeSysId);

gs.print("@change sysid"+changeSysId);

}

    var assIns = new GlideRecord('asmt_assessment_instance');

    assIns.addQuery('task.sys_id',changeSysId);

    // assIns.orderByDesc('sys_created_on');

    // assIns.query();

    if(assIns.get('415f1e131bde56106cb85204604bcba7')){

        gs.print(assIns.name);

    }

    var gr = new GlideRecord('asmt_metric_result');

gr.addEncodedQuery('actual_value=8^metric.name=Business Criticality^source_id=29a4b7181b2e5e106cb85204604bcb9e');

gr.query();

  if(gr.next()){

        gs.print(gr.actual_value);

}

I am able to get the instance but that is linked to some different metric type and  i want that particular assessment instance that is linked the the change request on which the risk assessment is calculated?

Also i am not able to query metric_type from assessment instance.

Sorry mate , scripting and me are not good friends, so tough to help here.
