Can a field in my form be used to poplulate the subtotal field in my PayPal element?

My service is a job posting board and I charge customers per day the job is listed. For example, A customer might have a job listed for 8 days at $0.25 per day for a total cost of $2.

Here is my form. 

https://form.jotform.ca/71032345799259

I'd like to know if I can have the price in my paypal element be populated by the field called "Total cost for this posting"

If not, can you please suggest a workaround.

Thanks,

Roger

This is indeed possible, what you need to do, is change the "Total cost for this posting" to a Form Calculation widget, add your calculation, and then follow the guide below to set your PayPal account to accept the calculation value. 

How to Pass a Calculation to a Payment Field

Alternatively, you can keep the "Total cost for this posting field" as it is, and add  a hidden Form Calculation widget, and set it to get the value from the cost field, and then continue as explained in the guide.

I have cloned your form, and made the changes, so you can clone it and start using it, via this URL:

Hello rogerfm,

I have moved your second question to a new thread so that we can address it separately. You will be answered in the following thread:  https://www.jotform.com/answers/1119524

Thank you!

can you please help me with one last step on this form? When a customer begins to fill out my form, the default value for my calculated field is 4317.25. I would like this field to be blank before the 'application date' field is filled. 

I have inspected to your form to know how it works. If I'm understanding your concern correctly, you just have to do two things to your form to make it work as you described in your most recent reply to this thread.

First, you need to set a default value on the "Total cost for this posting" field in your form.

And second, get the value of the "Total cost" Form Calculation widget from the "Total cost for this posting" field.

I hope this helps. If you need any further assistance, please feel free to contact us again anytime.

Thank you.
