Updating a Multiselect Lookup Field

Updating a Multiselect Lookup Field

I'm currently trying to update a multiselect lookup field in a record, but it's giving me the error {"code":3001,"data":{"ID":"3268991000041877010"},"error":["Invalid column value for Staff"]} . I've tried the list method and the collection method. The lookup field I'm calling from JobSheet and inputting are also using the same records/form. Here is the code I have so far:
  1. id1 = rec.Job_Sheet1.ID;
  2. info id1;
  3. addStaff = List();
  4. eventParams = Map();
  5. otherParams = Map();
  6. for each employee in input.Staff
  7. {
  8. addStaff.add(employee);
  9. }
  10. staffList = addStaff.toListString();
  11. eventParams.put("Staff",staffList);
  12. info eventParams;
  13. updateStaff = zoho.creator.updateRecord
  14. ("joshuabetty","atelier","All_Job_Sheets1", id1, eventParams, otherParams," creator");
  15. info updateStaff;
