jQuery need help with selection

[grandpajim]

Hi, I'm new to jquery, please bear with me. I created a page from code i found online. I have 2 divs, 1 with data from mysql, the other is empty. I can make a selection by clicking a checkbox, which each line has one, and then click a button and move all checked items to bottom div. I want to check all the items I've moved to the bottom div and post them to a processing page, but this is where it gets weird. let's say I check 3 lines, any 3, and move them down the first 3 in the top div are what's sent to the process page. This is the code I'm using.

$(document).ready(function () {
		// Uncheck each checkbox on body load
		$('#batch_content .selectit').each(function() {this.checked = false;});
		$('#lower_batchwin .selectit').each(function() {this.checked = false;});
		
    	$('#batch_content .selectit').click(function() {
			var userid = $(this).val();
			$('#user' + userid).toggleClass('innertxt_bg');
		});
		
		$('#lower_batchwin .selectit').click(function() {
			var userid = $(this).val();
			$('#user' + userid).toggleClass('innertxt_bg');
		});
		
		$("#move_down").click(function() {
			var users = $('#lower_batchwin .innertxt2').size();
			var lower_batchwin = $('#batch_content .innertxt_bg').size();
			
		//	if (users + lower_batchwin > 5) {
		//		alert('You can only chose maximum 5 users.');
		//		return;
		//	}
			
			$('#batch_content .innertxt_bg').each(function() {
				var user_id = $(this).attr('userid');
				$('#select' + user_id).each(function() {this.checked = false;});
				
				var user_clone = $(this).clone(true);
				$(user_clone).removeClass('innertxt');
				$(user_clone).removeClass('innertxt_bg');
				$(user_clone).addClass('innertxt2');
				
				$('#lower_batchwin').prepend(user_clone);
				$(this).remove();
			});
		});
		
		$("#move_up").click(function() {
			$('#lower_batchwin .innertxt_bg').each(function() {
				var user_id = $(this).attr('userid');
				$('#select' + user_id).each(function() {this.checked = false;});
				
				var user_clone = $(this).clone(true);
				$(user_clone).removeClass('innertxt2');
				$(user_clone).removeClass('innertxt_bg');
				$(user_clone).addClass('innertxt');
				
				$('#batch_content').append(user_clone);
				$(this).remove();
			});
		});
		
		$('#view').click(function() {
			var users = '';
			$('#lower_batchwin .innertxt2').each(function() {
				var user_id = $(this).attr('userid');
				if (users == '') 
					users += user_id;
				else
					users += ',' + user_id;
			});
			alert(users);
		});
	});
