Help : Javascript in report template

Question

Hi,
I created a report template named "MyFirstTemplate". In this template I use javascript to print an optionnel field named "COMMENTARY" when it is not empty here is the code :
<br><br>
<script language="javascript"><br>
if("#COMMENTARY#" != " - ") // because null caracter is replaced by " - "<br>
{     <br>
document.writeln('<tr>')<br>
document.writeln('<td class="t2data" colspan=6>')<br>
document.writeln('<font color="#7E587E#"><b>Commentary: </b></font>') <br>
document.writeln('#COMMENTARY#')<br>
document.writeln('</td>')<br>
document.writeln('</tr>')<br>
}<br>
</script><br>
<br><br>
My problem is :<br>
1. When commentary have " ' " caracter like : " It's a good deal ", I will have an error message like : ")" is missing on line... <br>
I guess it's on this line : document.writeln('#COMMENTARY#') .
Does anybody knows how to fix it ?
<br><br>
2. How can I know if the field is empty without using this " - " in
if("#COMMENTARY#" != " - ") ?<br><br>
Thanks a lot.<br>

Thank you ageller1, it works.
<br><br>
I use this :<br><br>
if(escape("#COMMENTARY#") != " - "){<br>
. . . <br>
var Commentary_esc = escape("#COMMENTARY#") <br>
...<br>
document.writeln('Commentary : ', unescape(Commentary_esc))<br>
...<br>
}<br><br>
Tks a lot<br>
