The documentation seems to indicate that you can set a default value for one or more hidden fields in the Form Builder. This does not seem to work, at least for linked records.
"Default value - In most fields, you can insert a default value that the form submitter will have to manually adjust, otherwise the default value that is set here will return that value with each form submission. This can be especially useful when hiding the field from submitters such as a hidden status field. The formatting of the default value that you enter will depend on the field type." (emphasis added)
I want to use this feature to create multiple unique forms from the same "registration" table for different events - the external client completes a record via the "Event A form" and the new record automatically specifies it is for "Event A" within a linked records field (connected to a separate "Events" table) that the external client never sees. A different client could fill in a different, separate "Event B" form and that new record would go into the same Registrations table but with "Event B" in the linked records field instead.
However, when I try to set a linked record field's default value in the Rules section of the Form Builder editing pane, then hide that field, Form Builder seems to undo the default value, such that the hidden field is blank in new form submissions. Why isn't this behaving as expected?
Example here: https://airtable.com/appvtFxwxKYmA0gwm/paglF4h5DPVKJECX1/form The 6th field "Event" is a linked record field and has a default value linking to a record titled "This is the name of a record in an Events table". I want to hide that field, but still have anyone hitting submit from this form / this url generate a record with that default value selected.
NB: This is not the same as setting a default value for the field in the base itself, such that the default value applies to all records. I want to set the default value only for records created via a particular Form Builder form.
