You can pass a variable in the URL (Get method) that calls the flash Movie

and use that variable in a goto command


href= ww.yourflashmovie.swf?scene=5


Beware that you have to pass the variable between the page that is calling

the flash HTML and the flash HTML which is calling the flash movie.  You can

do this a number of ways....


    1) create an HTML page for every scene in order for an outside page to

call this variable then pass the variable differently within each different

flash HTML, or

    2) pass the variable between the pages via some scripting language that

can pass variables such as JavaScript or even Perl....


I have gone with the first sloppier way because I didn't have the time to

learn how to pass variables the second way.


then at the begining of your movie use


Go to and Play (scene)   *click "expression" to use the argument within the

paranthasises as an expression.


Scene five will then be played


Watch out for two possible errors:


    1) don't use the Goto command on the first frame since Flash 4 doesn't

really have any code to tell you when data has been loaded....as long as you

have a preload movie or at least a couple seconds before the Goto is used

then the data should update your variable (also, declare your variable

beforehand)

    2) I am not sure why but I have had trouble more than once trying to

pass one variable at a time.....At least in Flash 5.  If it turns out that

you are getting the variable but it doesn't read correctly (in that it is

not read as a number for instance) just pass two or more variables.  I don't

understand why just one variable is so problematic, but I have not had a

problem with more than one variable being passed.
