Page Div align not showing correctly - asp.net

Question

I have a weird situation and believe that it must be easy for people to help me out on this specific issue. I have two divs on a child page that i want to show next to each other. I mean, One on left and one on right. After that, on the bottom of the screen I want to display a table that covers 100% width.
I have used float left on one div and float right on another div. Then i show the heading of the table on the bottom, then the table displays.
My problem is that the despite all my efforts the heading is displaying in between these two divs. Here is my code.
<div id="ContainerDiv" runat="server" style="width: 930px">
<div id="DivticketDetails" runat="server" visible="false"
style="float: left; width: 400px;">
<asp:Panel ID="PanelTicketDetails" runat="server" BackColor="#8B9FBE">
<h3 style="color: #FFFFFF; font-weight: bold; text-decoration: underline;">
Bowzer Details</h3>
<table border="1" cellpadding="0" cellspacing="0" class="myTable">
