Error message when running form code

[s_hellmann336921]

Hi,

I can run this form in a blank web page and it runs fine. Once I past it into my existing layout, I get the following error message:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent

(followed by a string of data pointing to my server and ending with)

/ContactForm_GMC/WA_ValidationToolkit/WAVT_ValidatedForm_PHP.php on line 3

Does anyone know why this might be happening?

Maybe a blank line in the code.. or maybe calling session_start after the session was already started.
