selectors only cycle when the state of the wire connected to the cycle input changes from on to off. A constant connection will not cycle. It looks like it should be cycling to the next output from the image you have, but that could be from the timing of the pause/setup. try attaching a pulser between each of the outputs and the OR gate.

The cycle input needs the signal to change from off to on to do anything. If the signal to that input is already active, it won't function until the signal turns off and on again. Generally the solution to this kind of problem involves a one-count counter set to reset itself at some point in your logic. The counter will send a signal for the minimum amount of time and then turn itself off so that the cycle input is ready for the next signal. I'm not sure exactly what you're trying to achieve with this selector, though. You want the second output to immediately activate the third and the third to immediately activate nothing? If you need events to rapidly occur in a certain order you may have better luck using a sequencer. Edit: Ooh, I'd love to see the timestamps on these posts! That was some coordination!

try attaching a pulser between each of the outputs and the OR gate. That ought to work, given that there's a frame of latency in the cycle input, so you'll get a rising edge (http://en.wikipedia.org/wiki/Signal_edge). Another solution would be not use the cycle input, but instead to connect output #2 to input #3, and output #3 to input #1, although it will cycle twice as fast using this method, which may be undesirable depending on the application. Ooh, I'd love to see the timestamps on these posts! That was some coordination! Here ya go... +--------+----------+---------------------+ | postid | username | timestamp | +--------+----------+---------------------+ | 927762 | tdarb | 2011-09-14 13:16:19 | | 927763 | Uncuddly | 2011-09-14 13:16:41 | +--------+----------+---------------------+

Not as close as I thought given that I checked for replies just before I sent it! I'll have to keep an extra tab open to facilitate the process.

How did you do that?! Or was it typed? Lol... That was the output of the following SQL query on the forum database... SELECT postid, username, FROM_UNIXTIME(dateline) AS timestamp FROM post WHERE postid IN (927762, 927763); No way I'd type that table by hand - too much effort. Anyways - this is getting somewhat off-topic...
