Re: [flexcoders] Repeater Control

[leds usop]

It looks like i overlooked what you really need. I
thought you want elements to APPEND 2 elements
(ormore) at a time. My bad. Anyway the code only
requires a few changes to achieve that result.
Although i really think use of repeater is not
necessary unless you want to display say, 30 elements
at a time? anyway here's the revised code:
