error at null

error at null

Hi,
*New to Zoho creator. 
Im trying to copy input from one field to another, and I'm getting "Error at NULL." 

ybeRecords = Yellow_Bird_Employee[ID in input.Salesperson_s];
ybeStringLists = ybeRecords.Email.getall();
if(input.ybeStringLists.contains("Mike Angel"))
{
input.Salesperson_Add = "Mike Angel";
}

  • Created or Edited
  • Successful form submission 
  • SalesPersons.s = employee lookup field

  • Thank you,
    Annette
