    Displaying error msgs in forms

    Hello

    I have a form with JavaScript validation. If the name is missing, or the email (etc), an error message appears to say: 'Please type your name', or 'Please type your email', etc. Unfortunately, these error messages appear on the same line at the top of the form, rather than on a line above each field. What this means is that if the site visitor fails to put in a name, email address, and message, the above error occurs at the top of the form: 'Please type your name Please type your email Please type your message'.

    What is the best way of solving this untidyness? To have the error display a message above each of the individual form fields? Are there any online examples or does anyone have alternate ideas?

    Thanks.

    Steve

    How about posting your current code/link and seeking help on fixing it?

    Thank for any help you cagive, abduraooft.

    Here is the JS file that seems to govern the form:

    Code:
    $(document).ready(function () {
    	$('#contact-form input.contact, #contact-form a.contact').click(function (e) {
    		e.preventDefault();
    		// load the contact form using ajax
    		$.get("data/contact.php", function(data){
    			// create a modal dialog with the data
    			$(data).modal({
    				closeHTML: "<a href='#' title='Close' class='modal-close'>x</a>",
    				position: ["15%",],
    				overlayId: 'contact-overlay',
    				containerId: 'contact-container',
    				onOpen: contact.open,
    				onShow: contact.show,
    				onClose: contact.close
    			});
    		});
    	});
    	
    	
    	
    
    	// preload images
    	var img = ['cancel.png', 'form_bottom.gif', 'form_top.gif', 'loading.gif', 'send.png'];
    	$(img).each(function () {
    		var i = new Image();
    		i.src = 'img/contact/' + this;
    	});
    });
    
    
    var contact = {
    	message: null,
    	open: function (dialog) {
    		// add padding to the buttons in firefox/mozilla
    		if ($.browser.mozilla) {
    			$('#contact-container .contact-button').css({
    				'padding-bottom': '2px'
    			});

    			$('#contact-container .contact-input').css({
    				'font-size': '.9em'
    			});
    		}
    
    		// dynamically determine height
    		var h = 280;
    		if ($('#contact-subject').length) {
    			h += 26;
    		}
    		if ($('#contact-cc').length) {
