hidden div not working properly

[abbylee26@hotmail.com]

<form name="RFO" id="RFO" method="post" action="neworde r.asp">
//arow is a hidden field I have made a text field for testing
<input name="arow" id="nrow" type="text">

<script language="JavaS cript">
if (document.RFO.a row.value)
document.write( "<div id='AccAmt'
style='visibili ty:hidden'>Amou nt</div></td>");
else
document.write( "<div id='AccAmt'>Amo unt</div></td>");
</script>

The value of "arow" is set to "1". And the column header "Amount" is hidden.
Depending on what the user does arow will change and "Amount" will become
visible. Lets say the value of arow is "2" and "Amount is visible when the
user hits the submit button.
The value of arow on the next page is "2"...but then the user sees he/she has
made a mistake and hits the "back" button.
On the original page the value of "arow" is still "2" but the column
header "Amount" is once again hidden.

Most certainly you do not need the ID attribute for a form element.

<script type="text/javascript">

Ask Google for the argument.

Possibly you meant

document.forms['RFO'].elements['arow'].value
[color=blue]

You are writing incomplete elements (</td> without <td>),
do not expect this to work. And you need to escape ETAGO
delimiters if they occur in script content embedded in
HTML: <\/

Same problem. And you should use braces for conditional branches
even if they contain only one statement. It eases maintenance.

This won't work because it results in

if (document.RFO.1 .value)

where 1 is not a valid identifier (such must start with a letter
or underscore). So you are looking for

if (document.forms['RFO'].elements[arow].value)

You have forgotten to tell what the error is.
"Does not work" is a useless error description. [psf 4.11]
