[FONT=Arial][SIZE=2]I have a question: I have a page in which the user will click on a watch video buton. This button is controlled via JavaScript (another programmer did this). He asked if it would be possible to have a swf with two buttons on it (on the same page where the JavaScrpt is): Low and high. The user should be able to choose one of the the two types of video (low or high resolution). The problem: 1 - The javaScript is sending the two variables with the low and high values. How my swf can access these variables. 2 - On [youtube.com](http://youtube.com), as I noticed, when you click on a link for a video, i.e: [COLOR=#003366]http://www.youtube.com/watch?v=65N\_1eSkKWg[/COLOR], it seems to me that the swf read that address and reacts acordingly. 3 - What kind o method inflash should I look into in order to start my programming? loadVars() or something like that? Thanks. [/SIZE][/FONT]
