How do i check if checkbox is checked then text is empty or not??

this is my rule:
if i didn't check checkbox then text can be empty,but if i checked checkbox,then text must be filled

i write like this,but it not working.

if (!theForm.Pagehot[0].checked){
if (theForm.DownDate.value == ""){
alert("¤U¬[¤é´Á½Ð¤ÅªÅ¥Õ!!");
theForm.DownDate.value = "";
theForm.DownDate.focus();
return false;
}
}

How do I write??
thanks for reply

if (!theForm.Pagehot[0].checked){
if (theForm.DownDate.value == ""){

! = NOT. Therefore, you are are saying 'if theForm.Pagehot[0] IS NOT CHECKED'...when you want it checked. Try this demo(just change the form element references):

<html>
<head>
<title>Untitled</title>
<script type="text/javascript">

</script>
</head>
<body>
<form action="javascript:alert('Success')" method="post" onsubmit="return validate(this)">
<input type="checkbox" name="chk" />Checkbox
<br />
<input type="text" name="txt"/>
<br />
<input type="submit" value="Submit" />
</form>
</body>
</html>
