hello,
i have the following code that writes the value of a check box to a textfield area.

When a user clicks a check box, the value is written to the text box.

However how do i get the value removed from the text box once the user unchecks the value ?

thanks
Afrika

[code]
var phoneValues = document.all.item("phone_nu2").value;
if (phoneValues.indexOf("yourValue") >= 0)
phoneValue.replace(/yourValue/gi, "") // this is a regular expression: /yourValue/gi. g = flag to
// replace all values not just first found, i = case insensitive compare
[/code]

yourValue is your phonenumber or some text you want to get rid of. not the name of your field.
