I'm using get items to interrogate a list, in which the items have 6 date of birth columns.
Problem is, it works fine if there's a date of birth in DOB column 1, but if DOB Column 2 is empty it fails
formatDateTime(outputs('DOB1'),'dd/MM/yyyy')
formatDateTime(outputs('DOB2'),'dd/MM/yyyy')

Any help would be grately appreciated
