passing form variables

I am trying to pass variables to a second page and must be forgetting something… Please help… Below is the code

[B]thumbView.html Code:[/B]

<script language=”JavaScript”>

function imageViewPage() {
var val1 = “”
var val2 = “”
imageChoice.imageName.value = val1
imageChoice.imageFile.value = val2
imageChoice.submit()
}

</script>

<form name=”imageChoice” action=”imageView.html” method=”POST”>
<input name=”imageName” type=”hidden” value=”Thumb 001.1″>
<input name=”imageFile” type=”hidden” value=”thumb001.1.jpg”>
<input type=”image” name=”Submit” src=”images/thumb001.1.jpg” width=”150″ height=”125″ alt=”” border=”0″ onClick=”imageViewPage()”>
</form>

[B]imageView.html Code:[/B]

<script language=”JavaScript”>
document.write(“&nbsp;<img src=’images/”+imageFile+”‘ width=’450′ height=’375’ alt='”+imageName+”‘ border=’0’>&nbsp;”) </script>

Also in #JavaScript _↴
