How to change price according to user selection?

hi
i was just wondering if there was a feature/widget
where if someone if applying with friends they have the option to express that somewhere in the form so i know that this particular person is applying not by themselves but with a friend?
I was thinking of a drop down box but i dont think that will cut it.
2. Is it possible to have 3 options and if someone ticks only the first box then the price is different, and if they choose the first 2 boxes it shows another price etc
Kind regards,
Jesse

If I understood you correctly, you would like to have a dynamic form changing fields according to user selection. 

For the first question, you can use single choice field and set options as "myself" or "with friends" or how you would like to set up. Then,you can use show/hide conditional logic to show or hide other fields according to user selection. 

Here is two different demo form for show/hide condition. Please feel free to clone it.

This is the user guide about our conditional logic feature:

For the last question which is about changing price according to user selection, you can achieve it by using update/calculate logic. This is the user guide where you can find more details about it.

The tricky part after set condition is to transfer total amount to a payment field. You may have a look at following user guide.

Hi i have attached image.
I was wondering if i can hide Price altogether until they select tax return or tax & super and they answered yes or no to the question is your gross income 20843.
In the preview the Price $75 is hidden but the price $39 is visible from the very start of the form (when all empty)
I dont know how the $75 is hidden until you choose "NO" to the question gross income below...

Thank you for the additional information.

Please note that the image you uploaded is not attached to your post. Please follow the steps here to attach your upload.

If I understood your question correctly, you would like hide both prices for the case:

- if the form is empty

- if the user is not select Yes option both for Tax return and income questions.

For the above case, the condition you need to set up is as following.  

The above condition is set according to this demo form. Here is the result of the form after set these condition. 

If this is not the thing you are looking for, please send us the form ID that you need to make changes on it with some more additional information regarding your request.
