Microsoft JScript runtime error: '(function name)' is undefined

Microsoft JScript runtime error: 'txtGivenName_OnFocus' is undefined
After adding what I thought was unrelated javascript code to a web page, I am suddenly getting errors that suggest that the browser cannot locate a javascript function that, to me, appears plain as day in design mode.
I'm thinking that this is a load sequence order problem of some sort. Originally, my script was at the bottom of the page. I did this with the intent of helping my site's SEO ranking.
When I moved the function to the top of the web page, the error went away. Now it is back.
I have a feeling someone is going to suggest a jQuery solution to execute some code only when the page is fully loaded. I'm I ignorant of jQuery. IfjQuery is given in the answer, please explain what I need to do (references, placement of script files) for VS 2010 RTM.
I am trying to set the focus to the first textbox on the webpage and preselect all of the text in the textbox

If I disable this Validator, the problem goes away:
<asp:CustomValidator ID="valSpecifyOccupation" runat="server" ErrorMessage="Required"
ClientValidationFunction="txtSpecifyOccupation_ClientValidate"
Display="Dynamic" Enabled="False"></asp:CustomValidator>
function txtSpecifyOccupation_ClientValidate(source, args) {
var optOccupationRetired = document.getElementById("<%=optOccupationRetired.ClientID %>");
if (optOccupationRetired.checked) {
args.IsValid = true;
}
else {
var txtSpecifyOccupation = document.getElementById("<%=txtSpecifyOccupation.ClientID %>");
args.IsValid = ValidatorTrim(txtSpecifyOccupation.value) != "";
}
}
