    Thank you, I am ok repopulating normal html fields by simply passing dynamic values to the "value" elements but my problem is with Paypal, tax and countries.


    From my website the price and the product id will be passed via php but I need a form where the user can click his country and according to this country, add 18% tax to the final price(before paypal) for all EU countries or NO vat for any countriesoutside EU. Final cost will be price(passed via php) + Tax(according to the chosen country).


    If this is not possible to be done quickly with jotform I will have to hard code this purely in php and jquery.


    Just asking your support as you may have a quick approach to it.

    Thank you for kindly providing more information on the task you have in mind.

    Upon examination of the tools and features our forms provide, I would say the quickest solution to achieve what you have in mind is through:

    1. Leveraging the form source code, in order to build up the concept of passing PHP data to it.

    2. Adding a dropdown menu for the countries, and assigning calculation values for the countries options that represent the tax percentage (18 vs 0)

    3. Setting up PayPal integration on the "User Defined Amount" payment type

    4. Calculating the price + tax as you explained above, into a field that will serve as the user defined field for the PayPal integration.

    Would that work for you?

    I think I will hard code it from scratch as I do not see the big gain of time with Jotform on this particular case.


    Thanks for your explanations.
