Hi:
What's the point of declaring the TEdit locally? Use a string
instead. Additionally, in Delphi [and any other OOP language) if you
want to use objects, you instantiate them first, as in Edit1 :=
TEdit.Create(nil);

I am attempting to update a table using a value that is displayed on a TEdit

Can someone tell me what I am doing wrong??
procedure TLoopBuilderForm.NewLoopButtonClick(Sender:
TObject);
var Edit1 : TEdit ;
begin
PSQLQuery1.Close;{close the query}
//assign new SQL expression Monitor
PSQLQuery1.SQL.Clear;
PSQLQuery1.SQL.Add ('Update P_ID.Loops');
PSQLQuery1.SQL.Add ('Set IDW_Loop_ID = + LoopNumberEdit');
PSQLQuery1.SQL.Add ('Where P_ID.Loops.Loop_Name = :Loop_Name');
PSQLQuery1.ParamByName('LoopNumberEdit').Value := Edit1.Text;
PSQLQuery1.Execsql;
end;
