Hey,  
I have a form that users fill out, and it sends me an email. To build this, I use PHP in the way described on a tutorial I found here on [Kirupa.com](http://Kirupa.com):

[http://www.kirupa.com/developer/actionscript/flash\_php\_email.htm](http://www.kirupa.com/developer/actionscript/flash_php_email.htm)

and it works quite well. However, I need to include some type of form validation where if the user fails to fill out certain fields, a text box changes to “ERROR: You must fill out the first 6 fields of the form to submit it.”  
I have tried using a series of If statements on the button before outputting the form vars to the email.php. Can anyone help?
