setfocus after alert in javascript

[amy]

I have a text box, after user input the value, a validate function
trigered. if the value is invalid, alert display, and also set focus
back to this control.

The alert displays, but when the click the 'OK' in the alert, the set
focus to this field does not work.

see the code bellow:

if (run!="" && IsNumber(run)==false && decimalinputvalid(run,2)==0 )
{
alert('wow');

//first try doen not working
(setFocus) ? document.papercaltbl.printorder.focus() : ""

//seconde try doen not working
this.getField("printorder").setFocus();

//third try doen not working
document.getElementById("printorder").focus();
}

Please give some advise. Thanks in advance.

Are you sure that
setFocus
is global?

the
this
will probable not refer to what you want.

I assume the focus error comes in Mozilla/Netscape?
Maybe you should put an url or or more info into your question?
