How can I send a calculated payment to paypal using a dropdown?

Another question... how do you alocate a separate price to each line of a Drop Down field? then add that choice to a calculation? Then send that to paypal?  and still get the info from the rest of the form that has no monitary value?

Did you mean that you wanted to send a set price from a dropdown to be used in a calculation that gets picked up by paypal?

Please see http://www.jotform.com/help/275-How-to-pass-a-calculation-to-a-payment-field for instructions and details.

You would basically first need to combine your paid dropdown choices with a calculation widget to generate the amount needed and then that would get carried over into paypal afterwards.
