    Inside of JotForm Builder you can set minimal and maximal value for Number field.

    Also you can set fields to be required.

    Here is a demo form I made http://form.jotformpro.com/form/51036117188957? 

    You can clone it if you want. 

    Hope this will help. Let us know if you need further assistance.
