Link to form not creating new Record

[mikewb20012000]

Hi All

I have a behaviour button, using "App: Go to another view within this app", with the target as "linktoform("Payments","Invoice No", [_THISROW],"Unit", [Unit],"Amount Paid", [Invoice Total])"

However, when the button is clicked, it opens the "payments" view, but does not open as a new record, just the list of existing records.

Have I missed anything?

I have another form with a similar button and it works fine.  I'm at a loss!
