Error in Javascript Key Press with Textbox

directxBOB asked
Last Modified: 2012-05-07
I have an ASP.NET Textbox

<asp:TextBox ID="tb1" runat="server" Width="300px" OnClientKeyPress="CalculateTotal(tb1.ClientID, tb2.ClientID, tb3.ClientID)">0.00</asp:TextBox>

When I run the code and and do the keypress, I get an error message saying that tb1 is not defined. I have also tried to do:

tb1.Attributes.Add("OnKeyPress", "CalculateTotal(tb1.ClientID, tb2.ClientID, tb3.ClientID)")

With no luck... I suspect i am making a rather simple mistake?
