请问这段代码哪里出错了

<script languahe="JavaScript">
var msg ="欢迎查看我的个人档案，请多提意见。谢谢！";
var interval=120
var spacelen=120;
var space10="";
var seq=0;
funcation Helpor_net(){
len=msg.length;
window.status=msg.substring(0,seq+1);
seq++;
if(seq>=len){
seq=0;
window.status=";
window.setTimeout("Helpor_net();",interval);
}
else
window.setTimeout("Helpor_net();",interval);

}
Helpor_net();
</script>
