null = zoho.creator added to my script on save

I have a deluge function that looks like this

  1. void AddToRecents(int EmployeeId, int CaseId)
  2. {
  3. [...snip...]
  4.     // no hits, insert new record
  5.     rvId = insert into Recently_Viewed
  6.     [
  7.     Last_Accessed = now
  8.     Employee = input.EmployeeId
  9.     Case = input.CaseId
  10.     ViewingUser = zoho.loginuser
  11.     ];
  12. }

But every time I save it and go back, a line is inserted (line 11 below).  That line, of course, is invalid and the function doesn't work.  Does anyone know why and what to do about it?

  1. void AddToRecents(int EmployeeId, int CaseId)
  2. {
  3. [...snip...]
  4.     // no hits, insert new record
  5.     rvId = insert into Recently_Viewed
  6.     [
  7.     Last_Accessed = now
  8.     Employee = input.EmployeeId
  9.     Case = input.CaseId
  10.     ViewingUser = zoho.loginuser
  11.     null = zoho.loginuser
  12.     ];
  13. }

Thanks.
