I have a form with 2 fields. First field is Text, second is Numeric. Is there a way if someone enters info into the text field, but an entry with that data already exists, to have the form sum the Numeric fields, thus maintaining 1 entry?
I would be fine if after it saw that a previous entry already exists, it copies the Numeric data from the older entry to this form and Sums the values....then deletes the older entry.
Thanks

Store the value of the previous entry in a hidden field using this: https://formidableforms.com/knowledgebase/get-a-value-from-an-entry/. Add the values in the current entry. Delete the previous entry after the new entry is saved. If you delete the previous entry before the new entry is saved, you won't have anything to refer to if the user decides not to submit the form.

What if it isn't the previous entry that I'm validating against, but any of the entries created?
Then you need to create custom code to gather the info you want to summarize and may need to use Ajax to determine the sum in real time.
