Hide Ui action button on incident form on state change

[PriyanshuVerma1]

We have a UI action button on incident form header called "Resolve Incident". We want to hide that button when State is changed to cancelled. For that I created a on change client script on incident table which is 

function onChange(control, oldValue, newValue, isLoading) {
  if (isLoading || newValue === '') {
    return;
  }
  
  // Check if the new value is "Cancel"
  if (newValue === '9') { 
    // Hide the UI action button
    g_form.setDisplay('d7e9b3701b6433004e9e97d58d4bcbcf', false);
  }
}

Now when I go to any active incident and change state to cancel, there is no change on form. Resolve button is still there. Can you guide me on how to achieve this

I raised a case with servicenow for this, thanks for helping me on this

I just checked the oob script include "IncidentStateSNC" in dev and sandbox. In this value of both closed and cancelled state is set as "7". But in oob instances i checked value of canceled state is set at '8' in script include, But the script is set at read only so I can't edit it. I guess that is causing the issue? Any suggestion on how to fix it

Try this 

(current.incident_state != IncidentState.CLOSED && current.incident_state != IncidentState.RESOLVED && current.incident_state != IncidentState.CANCELED) && (gs.hasRole("itil") || gs.hasRole("itil_admin") || current.caller_id == gs.getUserID())

Write a client script add a code

g_form.setDisplay('button_id',false);
