Disable Field not working from a Report

Disable Field not working from a Report

I am trying to disable certain fields from being edited, but when I access the record via the Edit button on a List Report, the disable function is not applied ?

Any thoughts
  2. for each REC in Access  [User_ID == zoho.loginuser]
  3. {
  4.     alert("Level : " + REC.Access_Level);
  5.     if (REC.Access_Level.toLong()  <  5)
  6.     {
  7.         disable Site_Name;
  8.         disable Seaware_Code;
  9.         disable Seaware_Detail;
  10.         disable Floor;
  11.         disable Location;
  12.     }
  13. }
