Pass LINKTOFORM Data to Edit Specific Row

[reserosg]

I'm building an app that passes a value via the LINKTOFORM() function and auto-populates the enum dropdown of a subsequent form. I'm running into issues however, in that the form creates a new row every time I use it, rather than editing a row with the same [Row ID]. In other words, when the user clicks a button to associate a given record to an existing parent record, I want to make it edit rather than add new records every time. 

I assume this is in the Row Key Options under the View panel, but I can't seem to make it reference what's in the auto-populated enum dropdown I mentioned above. Any suggestions?

Try instead LINKTOFILTEREDVIEW?

LINKTOFORM only works for new records. You can't pass potential values in to a form on an existing record. You can set those values to the record using INPUT() w/ a reference action.
