Pull Down Null Value

[Scott-Mc]

I've got a pull down field with a number of text items. Each item has a numeric value bound to it ranging from 0 to 15.

I'd like to provide an item that lets a user return the field to null in case an item is chosen in error.

Anyone know how this can be done?

Thanks.

Here's  one method, but I'll be interested if there's a more elegant way.

I provided an item made with a space character and this script:

if (this.rawValue = " ")

{

this.rawValue = null;

}
