   if (newValue === '') {
      return;
   }
var user=new GlideRecord('sys_user');
user.addQuery("sys_id", newValue);
user.query();
if(user.next())
{
alert(user.name);
var dep=new GlideRecord("cmn_location");
dep.addQuery("sys_id", user.location);
dep.query();
if(dep.next())
{
alert(dep.name);
    var yy=dep.name;
    g_form.setValue('comments',yy);
    
if(yy!='')
    {
    if(yy=='Americas')
        {
g_form.clearOptions('category');
g_form.addOption('category','ktlo','KTLO');
}
if(yy != 'Americas')
{
g_form.clearOptions('category');
g_form.addOption('category','project_work','Project/Project Task');
g_form.addOption('category','task_work','Task work');
g_form.addOption('category','admin','Admin');
g_form.addOption('category','meeting','Meeting');
g_form.addOption('category','ooo','Out of office');

g_form.addOption('category','time_off','Time off');
g_form.addOption('category','appointment','Appointment');
g_form.addOption('category','call','Phone call');
    
}

if(isLoading && !g_form.isNewRecord()){
g_form.setValue('category', yy);
}        
}
}
    else

Hi Chanikya,

I assume the field is drop down with None. If you want to set None then use g_form.setValue('<field>', '');

Mark Correct if this solves your issue and also mark Helpful if you find my response worthy based on the impact.
Thanks
