Why is Javascript ignoring the whole thing?

[dacloo]

A selectbox does the following event:

<select name="mb_functie" id="mb_functie" onChange="redirect(document.properties.this.options.selectedIndex)">


and the actual code is:

<script language="javascript">
<!--

var groups=document.properties.mb_functie.options.length
var group=new Array(groups)
for (i=0; i<groups; i++)
group[i]=new Array()


group[0][1]=new Option("wysiwyg_template_1 (Dit is de standaard pagina.)","1")
group[1][1]=new Option("wysiwyg_template_2 ()","1")
group[1][2]=new Option("news_template_1 (Een pagina voor functie 2)","2")
group[2][1]=new Option("news_template_2 (News template 2)","2")
group[2][2]=new Option("forum_template_1 ()","3")
group[3][1]=new Option("forum_template_2 ()","3")


var temp=document.properties.mb_sjabloon

function redirect(x){
for (m=temp.options.length-1;m>0;m--)
temp.options[m]=null
for (i=0;i<group[x].length;i++){
temp.options[i]=new Option(group[x][i].text,group[x][i].value)
}
temp.options[0].selected=true
}

//-->
</script>

But javascript isn't giving me any errors, but doesnt do anything visually!

What's wrong? Thank you.


ps:

When changing selectbox to the following:

<select name="mb_functie" id="mb_functie" onChange="redirect(this.options.selectedIndex)">


I get: temp.options in null or not an object.

OKay....Found it out...after two friggin' days! (not fulltime on it though :-)

The arrays were wrong....didn't start with [0][0]....

I get: temp.options in null or not an object. It's just "this.selectedIndex" -not- "this.options.selectedIndex"
