@xyntec: there is the delay ... that means it will automatically rotate the leds for an time of some milliseconds ... but that isnt the key,
press button = switches the next led on /the lastone off .. but just if the button is pressed .. delay is unusual here 
@rob: the leds rotate if i press the button, BUT the run of their own .. because the delay ... thats exactly my problem .. the use of delay or intervall isnt the right way .. mmh
