Counting the number of values selected in a list box

[sredden1]

I'm trying to add a counter to a form that tells the user how many values have been selected from a list box... I tried adding a FormCalc formula to a calculate event in the "counter" field as follows:

count(form1.#subform[0].ListBox1.rawValue)

But for some reason it's not adding them up. It only gives me a value of 0 when none are selected, or 1 where any number of selections are made.

Can anyone help me out?

Thanks in advance

Try putting this in the calculate event of your counter field:

var num=0;

for (var a=0;a<ListBox1.items.nodes.length;a++){

if (ListBox1.getItemState(a))

  num++;

}

this.rawValue=num;

Exit the list box and the field will calculate.
