Pass a calculation to stripe payment

Hi. i would like to know if i could pre-selet a stripe product depending on a previous answer.

Basically, i made a form where users personalize their order through a wide variety of selection.  The problem the users don't want to enter their payment information before they personalized their information.

i would like them to choose with type of product they want before and depending on the answer, pass on the cost to strip or preselect a product at the end of the form

Is that possible?

Conditions cannot be used to select products in the payment field.  For the setup you are looking for, you would need to set up your products using regular fields (single choice, multiple choice, number fields) outside of the payment field.  You can assign those options calculation values:

Total up those values using a calculation field:

Then pass that total to the payment field:

This way, you can use conditions to make selections.
