Input Text Error in letterSpacing


I am doing a mailing list sign up and my input text doesn’t seem to have the letterSpacing settings working.

My input text’s instance is set to Semail.

I don’t have any var set to it.
I am using loadVariables to interact with the PHP.

I am using the codes below to set its letterSpacing but it’s not working.[INDENT]var email_fmt:TextFormat = new TextFormat();
email_fmt.letterSpacing = 1;
[/INDENT]My other dynamic text are working fine for the letterSpacing part. I am using CS 3 and Flash Player 10.

What could be the reason? Is input text different from dynamic text?

Thanks in advance for the help.
