This sets which of the available price rows the rate applies to. If you are not showing only one rate multiple offers for your rooms leave the default value "1" for all rates. Change ONLY if you are using EXTRA PRICES (SETTINGS -> BOOKING PAGE -> ROOMS -> EXTRA PRICES ) this set to offer multiple prices (e.g. standard rate/non refundable rate, packages). Select which price row this rate should apply to.1
