how to post variables between flash and asp

Hello, I wonder do you have any idea about how to post the variables between asp file and flash file. Bucause I have code in asp file like choosing a picture from a form and I want to pass that image back to the flash page. How could the code be?

<FORM name="myform" action="designpage_colormap.asp" method="post">
<input name="color" type="radio" value="001">Red
<input name="color" type="radio" value="002">blue
<input name="color" type="radio" value="003">marine
<input name="color" type="radio" value="004" selected>white

<input name="choose" type="submit" value="choose">

</FORM>

THanks in advance !

If you are using FlashMX (6.0) then look at the LoadVars Class.

It can post to a server side page, as well as set parameters like what to do with the answer that comes back.
