Need Urgently Help

Hi

I am javacript function in aspx page
function check()
{
var letters = window.document.forms(0).txtItem1.value.length+1;
if (letters <= 16)
{
window.document.forms(0).txtItem1.focus()
}
else
{
window.document.forms(0).txtItem2.focus()
}
}
</script>

I want to move focus on 24 textbox( txtItem1 to txtItem24)
can any one tell me how should i move focus on 24 Textbox.
when user eneterd maxlength in each textbox. as above.

What i understood from your question is, the moment user tries to enter more then the maximum allowed as per your logic the Focus should move to text24 field.

If i am correct then try with , use onkeypress="check()" in your field text1.
