Что-то у меня крыша не едет. Помогите, что не так?

dset_acc->Close();
dset_acc->ParamByName("CTR1")->AsInteger = ID_CONTRACT;
dset_acc->Open();

dset_acc->Edit();
	dset_acc->First();

	for (;!dset_acc->Eof;) {
if (dset_acc->FieldByName("ID_WORK_FOR_PAYMENT")->AsInteger == 1) {
			dset_acc->FieldByName("COUNT")->AsFloat = dset_weight_rc->FieldByName("COUNT")->AsFloat;
		        dset_acc->FieldByName("SUMMA")->AsFloat = 
dset_acc->FieldByName("PRICE")->AsFloat*
dset_acc->FieldByName("COUNT")->AsFloat;
			dset_acc->FieldByName("SUMMA_TAX")->AsFloat = dset_acc->FieldByName("SUMMA")->AsFloat*
dset_acc->FieldByName("MULTIPLIER")->AsFloat;
		}

if (dset_acc->FieldByName("ID_WORK_FOR_PAYMENT")->AsInteger == 5) {
			dset_acc->FieldByName("COUNT")->AsFloat = dset_mwrk_sum->FieldByName("C1")->AsFloat;
			dset_acc->FieldByName("SUMMA")->AsFloat =
dset_acc->FieldByName("PRICE")->AsFloat*
dset_acc->FieldByName("COUNT")->AsFloat;
			dset_acc->FieldByName("SUMMA_TAX")->AsFloat = dset_acc->FieldByName("SUMMA")->AsFloat*
dset_acc->FieldByName("MULTIPLIER")->AsFloat;
		}

if (dset_acc->FieldByName("ID_WORK_FOR_PAYMENT")->AsInteger == 10) {
			dset_acc->FieldByName("COUNT")->AsFloat = 0;
			dset_acc->FieldByName("SUMMA")->AsFloat = uz;
			dset_acc->FieldByName("SUMMA_TAX")->AsFloat = dset_acc->FieldByName("SUMMA")->AsFloat*
dset_acc->FieldByName("MULTIPLIER")->AsFloat;
		}

		if (dset_acc->FieldByName("ID_WORK_FOR_PAYMENT")->AsInteger == 8) {
			dset_acc->FieldByName("COUNT")->AsFloat = tkm;
			dset_acc->FieldByName("SUMMA")->AsFloat = tkm*dset_acc->FieldByName("PRICE")->AsFloat;
			dset_acc->FieldByName("SUMMA_TAX")->AsFloat = dset_acc->FieldByName("SUMMA")->AsFloat*
dset_acc->FieldByName("MULTIPLIER")->AsFloat;
		}

		dset_acc->Next();
	}
	dset_acc->Post();

Сам разобрался, можно закрывать. Надо было на каждую операцию отдельно ставить Edit и Post.
