Hidden Fields Issue Can't Post
Hi all,

I'm going mad!! I simply want to say if a field is blank, don't display the information. So, the following should be right:
Code
 <script type="text/javascript">  
    
var strvalue = "$lfield38$";    
if(strvalue!="")  { 
 document.write('<table border=0 width=100% cellspacing=0 cellpadding=2');  
 document.write('<tr>'); 
 document.write('<td bgcolor="#EEEEEE"><b>&nbsp;Property Overview</b></td>'); 
 document.write('</tr>'); 
 document.write('</table>'); 
 document.write('<p class="maintext">$lfield38$</p>'); 
}  
</script>
Ideally & for neatness, I think the following should work & be correct but neither function!
Code
 <script type="text/javascript">  
     
if($lfield38$!="")  { 
 document.write('<table border=0 width=100% cellspacing=0 cellpadding=2');  
 document.write('<tr>'); 
 document.write('<td bgcolor="#EEEEEE"><b>&nbsp;Property Overview</b></td>'); 
 document.write('</tr>'); 
 document.write('</table>'); 
 document.write('<p class="maintext">$lfield38$</p>'); 
}  
</script>

Hi Jarvis

Thanks for posting!

First thing here is that you'll probably want to us:

$lfield38_je$

That little moddifier makes things work better if you are using the values in JavaScript.

Next, for this bit:

if($lfield38$!="")

Could you try:

if("$lfield38$" != "")

An even more organized way would be:

if("$lfield38$")

but the last two are both the same.

I think that should get you going. The way you had it before, the JavaScript was trying to use your placeholder as JavaScript variable. Putting the quotes around tells it to evaluate that as a string.

Give it a shot and let me know how you make out :).
