Hmmm
Looks like it may well be the email address.
(www or mail.)pd.jaring.my will not resolve as valid domain for me.
Sending mail to info@pd.jaring.my bounces back also.
Tested this with TraceRoute and NeoTrace.
You can try by using the tracert.exe command in 2000 or XP
(Start->Run-> cmd -> tracert then type the domain.)
So yes, your email is the reason it's failing to process the form correctly for reason it does not resolve (for me anyway)
Appologies to Eddy

I can only suggest another email address be tried?
