Allow conditions to force a required Square product selection

Hi guys,

I have put together a form for my business which has Square payments. I have a number of conditions and fields which help the form determine if the order being placed is being made by a specific cut-off date. For orders after the cut-off date I need to add a late fee for shipping but I cannot for the life of me find a way to automate this in to the form.

I understand I can switch from products in Square to a pre-defined total but this is messy and doesn't work for me.

Is there anyway at all to force a product selection in Square based on conditions? I can see that I make a product 'required' in Square but it's either on or off and doesn't appear to be conditional.

Thanks

I would recommend you to instead manually perform the calculations, this will allow you to control the products as you need and you may also add the additional fee based on  the date (with conditions).
