trigger validation rule on task if field on parent record is blank

Hello,

I am not that great with Apex. I need a validation rule to fire if someone tries to complete a task without filling out a field on the parent record.

The requirements are:

Trigger on Task when Status = Completed AND (Task_Reference__c = 'L-739-5' OR 'L-739-10')

If Judgement Date is blank, THEN prevent from saving, fire validation rule message.

Here is my code:

trigger trgTaskJudgementDateCannotBeBlank on Task (before insert, before update) {

public Id trialId;

    for(Task t:Trigger.New){

        if(t.Status=='Completed' && (t.Task_Reference__c =='L-739-5' || t.Task_Reference__c =='L-739-10')){

            trialId = t.WhatId;

        }

    

        

    Trial__c[] jdate = [select Judgement_Date__c from Trial__c where id = :trialId];

    

    if(jdate == NULL){

        t.addError('Please enter a judgement date for this trial record');

    }

    

    }

}
