<div id="contact-area">  			  						<form method="post" action="contactengine.php" name="myform" onsubmit="return contact-validation()">  						<label for="name">name:</label>  						<input type="text" name="name" id="name">  				  						<label for="company">company:</label>  						<input type="text" name="company" id="company">  	  						<label for="email">email:</label>  						<input type="email" name="email" id="email">  				  						<label for="message">message:</label>  						<textarea name="message" rows="20" cols="20" id="message" title="your message | max 300 characters"></textarea>    						<input type="submit" name="submit" value="submit" class="submit-button">  						</form>  			  					<div style="clear: both;"></div>  			  					</div>

this wrong:

onsubmit="return contact-validation()"> 

1. you have no javascript method called contact-validation().

2. even if did, dashes not valid in function names.

try instead:

onsubmit="return validateemail()">
