OMV dns server settings using web gui

i wanted to setup 2 dns servers - my ISP server (primary), then my router (secondary)
i have not yet found anything that states how to enter multiple dns servers in the gui...
i entered them as 202.142.142.142,192.168.1.1 in the gui interface - is that correct or should i separate by a space or comma+space or something else ??

when i tried that a popup advised that separator should be , or ; (which did not occur the first time). I then used , between and then i could save the settings with the list of dns servers. issue solved!
