I've checked your JotForm see that the discount is set using a number field. Since it is a number field, it is not allowing to display $ symbol. The field is displaying decimal points as soon as the calculation values are entered. If you want to display $ symbol with the calculated value, you may consider using a text or Form Calculation widget instead of a number field.
Please see the demo form that can help you understand the differences.
Hope this information helps!
Perfect. Works like a charm. thank you.
