Trigger will not compile

Question

I wrote the trigger which compiles with errors. The errors are:
Error(9,5): PL/SQL: SQL Statement ignored
Error(9,12): PL/SQL: ORA-00903: invalid table name
Error(14,5): PL/SQL: SQL Statement ignored
Error(14,12): PL/SQL: ORA-00903: invalid table name
and so on for the other lines that reference a table. I tried prefixing the table with the schema name and removing the alias but it will not compile either way. Is there something obvious that I don't see?
Create Or Replace Trigger ERR_EVACUATION_TAB_BU
Before Update On Err_Evacuation_Tab
For Each Row
Begin
If V('APP_USER') Is Null Then
:new.last_update_by := USER;
ELSE
:new.last_update_by := V('APP_USER');
END IF;
:New.Last_Update_Date := Sysdate;
If :New.Evacuated_Ind = 'Y' And :New.Entire_Evac_Ind = 'Y' And :New.Remaining_In_Apt = 0 Then
Update Table Err_Impaired_Tab Eit
Set Eit.Evacuated_Ind = 'Y'
Where Eit.Location_Code = :Old.Location_Code;
-- And Eit.Rent_Id_Tenant_Number = :Old.Rent_Id_Tenant_Number;
Update Table Err_Lifesustain_Tab Ert
Set Ert.Evacuated_Ind = 'Y'
Where Ert.Location_Code = :Old.Location_Code;
-- And Ert.Rent_Id_Tenant_Number = :Old.Rent_Id_Tenant_Number;
else
Update Table Err_Impaired_Tab Eit
Set Eit.Evacuated_Ind = 'N'
Where Eit.Location_Code = :Old.Location_Code;
-- And Eit.Rent_Id_Tenant_Number = :Old.Rent_Id_Tenant_Number;
Update Table Err_Lifesustain_Tab Ert
Set Ert.Evacuated_Ind = 'Y'
Where Ert.Location_Code = :Old.Location_Code;
-- And Ert.Rent_Id_Tenant_Number = :Old.Rent_Id_Tenant_Number;
End If;
END;
