I am trying to clear an option box

[caseye]

I am trying to clear an option box the following loop works but only clears the firs two entries then

SelSitesLength = document.reportbuilder.SelSites.options.length;

for(i = 0; i < document.reportbuilder.UnSelSites.options.length; i ++)
{
site = null;
siteSplit = null;
if(document.reportbuilder.UnSelSites.options !== null)
{
site = document.reportbuilder.UnSelSites.options.value;
siteSplit = site.split(&quot;,&quot;
if(siteSplit[0] = state)
{
document.reportbuilder.UnSelSites.options = null

}
}
}

Please enclose your code in [ code ] and [ /code ] tags (without the spaces). Especially if you use i as an array subscript. Mainly because

[i]

is the TGML tag to turn on italics, which is why your code turns italic halfway thru. If you use the code tags, you can say

[i]

with no problem. Tracy Dryden

for(i = 0; i < document.reportbuilder.UnSelSites.options.length; i ++) {
 site = null;
 siteSplit = null;
 if(document.reportbuilder.UnSelSites.options[i] !== null) {
  site = document.reportbuilder.UnSelSites.options.value;
  siteSplit = site.split(&quot;,&quot;);
  if(siteSplit[0] = state) {
   document.reportbuilder.UnSelSites.options = null
  }
 }
}

Line 4, where you see

 if(document.reportbuilder.UnSelSites.options[i] !== null)

The condition be

!=

rather than

!==

And nested within it, line 7

  if(siteSplit[0] = state)

That condition should be

==

rather than

=

Further than that, I can't help unless you provide more code.
