I'll have a go. (I have two 550EXs, but I assume that the 420EX will be similar except for power.) Set lower switch on 420 to Slave, and on 550 to Master. This automatically sets the 550 to group A. Turn 550EX ON at main switch. Press SEL/SET repeatedly until Ratio blinks. Press + or - until A:B appears plus a ratio scale. Now press + or - until desired ratio is set. Probably 1:2 or 1:4 will be OK for getting the 550EX to act as a fill-in. Check that both guns are set to same channel; (set similarly to above) 1 is probably best if the 420 doesn't have this as an option. (Incidentally, if you want to adjust settings on the Slave mode gun, press the MODE switch for > 2 seconds.) Hope this helps - I've got some ratio examples on my website, but no further instructions!
