Does WWWForm works for flash building?

I’m trying to send email by using small php script on my server.
Information for this script I pass by WWWForm.
But is works on standalone build. When I try to do build for flash I see error BCE0018.
I’m not sure if WWWForm is implemented to build flash?

I have only a few scripts in this same folder to it shouldn’t be wrong compilation order.

I’ve found that so far WWW class is not supported in flash.
Possible solution instead of WWW class is to create your own ActionScript file and paste it in ‘ActionScript’ folder in ‘Assets’.

in Unity you can use ActionScript class to pass some parameters to *.as file.
