First time FMC won't give me V speeds

[Guest]

What did I do wrong? Everything was entered correctly, but I clicked on V1, V2 buttons and no number was entered automatically. I tried with 5 flaps, 10 flaps. Nothing. No disconnect, pref was complete... what gives?

Did you check weight, fuel etc on INIT REF page? Also note that the V-Speeds get deselected when you change Departure procedure or runway.- Neeraj

Everything is setup OK. It seems when I select KSFO runway 28L for departure it works... but 28R doesn't? May be my imagination but I tried it again tonight after work and same problem!!! Oh well
