	//How to use
    //Create a text box and a maching lable underneath
    //For argument sake txtTextBox and lblLable
    //lblLable text  = “”
    //add the onkeypress and onkeyup events for txtTextBox
    //e.g. 
    //<asp:TextBox ID="txtTextBox" onkeypress="return CheckTextCount(this,'ctl00_ContentPlaceHolder1_lblLable',250);" onkeyup="return CheckTextCount(this,'ctl00_ContentPlaceHolder1_lblLable',250);" runat="server" Height="60px" TextMode="MultiLine" Width="200px">
    //</asp:TextBox>
    //<br />
    //<asp:Label ID="lblLable" runat="server"></asp:Label>
