getDisplayValue returning value from wrong field

[___miked___]

I have multiple fields on a form.   I'm trying to get the value of a choice-list field called 'patient_category'.   But, the following code always returns the value of another field on the form -- the patient_name field.   regardless of what field I specify as the getDisplayValue parameter, the system always returns the value of the patient_name field. I'm totally new to scripting in ServiceNow so am wondering what I am missing.    

function onChange(control, oldValue, newValue, isLoading) {

      if (isLoading || newValue == '') {

          return;

    }  

alert(g_form.getDisplayValue('patient_category'));

    }

Thanks in advance for your help.

Are you sure? Whats the value you get, what did you expect to get and what is the value in patient_name field?

Pretty sure.   I deleted the script and re-entered it (for no apparent reason) and changed the name of the field from 'patient_category' to 'service_category'.   The code now looks like this:

function onChange(control, oldValue, newValue, isLoading) {

      if (isLoading || newValue == '') {

          return;

    }

      alert(g_form.getValue('service_category'));

      alert(g_form.getDisplayValue('service_category'));

    }

The first alert returns a hex string -- probably the sys_id.

The second alert returns empty now.

The actual value in the service_category field is "Large Animal," which is what I was expecting to see. The value in the patient_name field is "Roscoe." So not sure what is happening now.

Hi Mike,

Try changing the name of field and check.

Change patient_category To u_patient_category

function onChange(control, oldValue, newValue, isLoading) {

      if (isLoading || newValue == '') {

          return;

    }

alert(g_form.getDisplayValue('u_patient_category'));

    }

If it wont work, post the complete screen shot of script and the form

Thanks for the reply.   Unfortunately, changing the field name didn't work.
