If the 3 label amount has no value the button is disabled,
otherwise if any of the 3 label has a value then the button is enabled

            int.TryParse(text.Text.Trim(), out i);
            return i;
        }
para sa iba na di alam
1. i ctrl+click yung mga label
2. sa properties iclick events (kidlat na icon)
3. sa events hanapin ang TextChanged
4. itype ang text_changed habang nakaselect yung tatlong label
