Hi @TanujB ,

oldValue? looks like an onChange Client script 

select you tableName and field if it's on table level

select catalog name and variable name if on catalog form level

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue === '') {
      return;
   }

   g_form.showFieldMsg('state', 'Previous state was: ' + oldValue, 'info');
   
}

please share your requirement in details (with some screenshots)

if the above doesn't work

Please mark my answer as helpful/correct if it resolves your query.
