    I have only one product. it cost $35.

    I want to have the user enter a quantity in a number field, then (using PayPal payment) multiply the product cost by the number entered. Then this is the total cost and sent through Paypal.


    Number Field - entered 3

    in the PayPal (only one product at a cost of $35),  3 x $35 totals $105. The $105 is processed via PayPal.

    I checked your form and I see that it is multiplying the quantity and product's price:

    What sevkiyontem said is correct, here is more detailed instruction if you want more customized product list:

    1. Create one Form Calculation field in the form:

    2. Add one text box for quantity and one checkbox for your product:

    3. Now we will set that checkbox value is 35:

    Go to Setting of the checkbox field:

    And set Calculation value to 35:

    4. In the form calculation, we will jus do the actual multiplying of the product and quantity:

    Go to wizard of the form calculation:

    And just multiply your checkbox with quantity field:

    5. Finally, we will pass Form calculation field to PayPal:

    Hope it helps.
