[flexcoders] Re: Value of AS variable dissapearing

[haykelbj]

As Alex said the remote procedure call is done asynchronuously so you
can't put the 'if' statement directly after the call, you have to do
it in the result handler function.

So you have to move this code

---
if (this.bEMail == true )
{

      ... give error message/handing duplicate...

Etc...
---

to the remote_result function (or put it in a function and call it
from the handler)! Anyway you have to wait for the result!
