freetextbox 的问题

三步添加我也加了 把freetexBox控件放上去就提示错误..
类型"FreeTextBoxControls.FreeTextBox"的控件“FreeTextBox1”必须放在具有runat="server"的窗体表记我的代码
</form>
    <form id="form1" runat="server">
    <table width="90%" height="336" border="0">
<tr>
 <FTB:FREETEXTBOX id="Freetextbox1" runat="server" Width="100%" Height="100%" 
ImageGalleryPath="UpImages"> </FTB:FREETEXTBOX> 
  
    <td>
        &nbsp;</td>
    <td>&nbsp;</td>
  </tr>
 
</table>
    </form>
