How to allow user to select product or input custom donation amount in paypal tool?

Thank U for responding to my earlier question. Trying to follow the instructions.  It said that my field "Registration Type", that you need to charge your user based on this field selection. What should the field selection be on conference registration? It is not a product, subscription... we do have an option where a user can define their amount and there is an opt for them to make a simple straight donation... but which one Payment Type should we select when trying to insert our Paypal info to link/integrate it into the form so that we can accept payments?

Also tried to insert a Hover Text for each option but it seems to take only one. Will U please explain to me how to do this?

Hello TeeFoxx,

I am not sure if I have understood your question correctly. Do you mean to say that you want to allow your users to select registration type or input donation amount to process payment. Is that correct?

I did check your form and found that you have added other option in radio button option to calculate the custom donation amount. Please note that it is not possible to add other textbox value in form calculation. 

The only option I can think of is to add a textbox field in form to accept donation amount and display it only when user selects donation as "Registration Type". Please take a look at the following cloned form where I have added the donation textbox and see if this is what you wanted to achieve:  https://form.jotformpro.com/71990641665970

Feel free to clone this form for a closer look. The following guide should help you in form cloning:  https://www.jotform.com/help/42-How-to-Clone-an-Existing-Form-from-a-URL

Hope this helps.

Do get back to us if you need any other changes.

Thank you!
