how to remove all item ?

[tyris]

hi all
i do have a mutiple select box and an array. i need to make a function that will remove all the things i have added.
when i added my items i incremented a var called number

function add() 
{ 

boxSelectedCond.options[number] = new Option(toto + " " + tata + " " + tutu ,number);
storeQuery[number]= new Array(toto,tata,tutu);
number ++;
}

and here is my delete function that is not working:

	for (i=0; i<number;i++)
	{
		document.forms[0].Sel_cond.options[i]= null;
		storeQuery[i] = new Array();
	}

what's wrong ?

Best regards X-),

Try this

for (var i=document.forms[0].Sel_cond.options.length-1; i>=0; i--)
{
  document.forms[0].Sel_cond.options[i] = null;
}
document.forms[0].Sel_cond.selectedIndex = -1;
