checking if change tasks have been approved before requesting approval for a change request

[donatello]

I am trying to write a business rule to check all change tickets to make sure that they have been approved before a change can be placed into pending or "requested for approval"". my script is not working for some reason and I would love if the community would help me out. Thanks in advance

function onBefore(current, previous) {
   checkChildTasks();
function checkChildTasks() {
       var grChild = new GlideRecord("change_task");
       grChild.addQuery('change_request', current.sys_id);
       grChild.addQuery('Approval',"CONTAINS","approved");
       grChild.query();
while(grChild.next()){   
       if (grChild.result == "approved" || grChild.result == "skipped")
       answer = true;   
       else{   
       answer = false;   
       return;   
   }   
   }   
}   
}

function onBefore(current, previous) {
   checkChildTasks();
function checkChildTasks() {
       var grChild = new GlideRecord("change_task");
       grChild.addQuery('change_request', current.sys_id);
       grChild.addQuery('Approval',"CONTAINS","approved");
       grChild.query();
while(grChild.next()){   
       if (grChild.result == "approved" || grChild.result == "skipped")
       answer = true;   
       else{   
       answer = false;   
       return;   
   }   
   }   
}   
}

Here you go

function onBefore(current, previous) {  

  if(checkChildTasks()=="true"){

current.setAbortAction(true);

}

function checkChildTasks() {  

      var grChild = new GlideRecord("change_task");  

      grChild.addQuery('change_request', current.sys_id);  

      grChild.addQuery('approval',"approved");  

      grChild.query();  

if(grChild.hasNext()){      

      return true;

  }      

  }          

}

thanks but that did not work, I when I click on request approval it still goes to pending with the change tasks not approved

Can you post the screenshots of your business rule and your business rule conditions
