Re: Javascript - changing button text

the javascript code is placed to high in the page
the browser executes it before the buttons at the bottom are created

place the folowing code after the end of the form
function cbt(letter, newText) {
 var buttons = document.forms[0].elements[session + "/BUTTON.999-999=*" +
letter];
 for (var i=0;i<buttons.length;i++) {
  buttons[i].value = newText;
 }
}
cbt('E', "Enter/OK");
cbt('U', "Earlier");

try mozilla browser http://www.mozilla.org, it has a much better javascrit
debugger than IE
