Change cursor focus

[OhLordy]

How do you set where the cursor is focused?
I have a simple validation script however after the alert box is displayed and the user clicks OK the cursor is focused on the next form element. I want it to be displayed on the one that was just looked at.
Thanks in advance

Use focus()

this function is supported by pretty much all HTML elements that can accept keyboard input...

e.g.
document.formName.myTextBox.focus();
