Making a circle larger, and then smaller

Hi!\r\rI want a circle to get large. No problem:\r\ronClipEvent (enterFrame) {\r if (_xscyle<200) {\r _xscale+=10;\r }\r}\r\rbut now: when the circle has reached the desired size I want him to shrink back to e.g. 150\r\ronClipEvent (enterFrame) {\r if (_xscyle>150) {\r _xscale-=10;\r }\r}\r\rI have problems because at a certain time both if-conditions would be fullfilled and nothing happens.\rIdeas?\rTHX\r\rHartwig

Couldn’t you just make a tweening movie clip to get round it?\r\r - Kit
