I'd like to make a fundraising form

Hi, I am trying to set up an auction jotform for a fund raiser for our school this year. I have the site built and have the "your bid amount" and "current bid amount" options ready to go. I have created the "current bid amount" as a calculation that will auto-populate with the "your bid" amount once they enter a bid. My question, the submission goes through correctly and I can see it on my submissions list but the next bidder does not see it populate The Jotform. How can I make that work? For example, if a person bids $100 on item 1, it populates and shows that bidder, $100 in current bid. They submit. The next person comes along. It does not show the $100. It has reset as blank again. Is there an easy fix for this other than me sitting in front of the computer for the entire auction and updating each "default value" for "current auction" myself? The link to my jot form is https://form.jotform.com/202395055922960 if that is easier to see what I'm talking about. Thank you.

Thank you for contacting us.

I'm afraid it's not possible to use the data from a previous submission and update the form according to that, that's why the form always "resets" to blank.

Please let us know if you have any more queries, thank you.
