Javascript checkboxes and hidden fields

Thank you try67, I will have a look. I have the check boxes working automatically, and I have a script that can switch the fields off, but when I click NO, it switches the Yes box off, but I have to click no again to get the text fields to switch off.

Below is the code:

if (this.getField("CheckBox8").value=="On") {

this.getField("Text89").readonly = true;

this.getField("Text90").readonly = true;

this.getField("Text91").readonly = true;

this.getField("Text92").readonly = true;

this.getField("Text93").readonly = true;

this.getField("Text94").readonly = true;

this.getField("Text95").readonly = true;

this.getField("Text96").readonly = true;

this.getField("Text97").readonly = true;

this.getField("Text98").readonly = true;

this.getField("Text99").readonly = true;

this.getField("Text100").readonly = true;

this.getField("Text101").readonly = true;

this.getField("Text102").readonly = true;

this.getField("Text103").readonly = true;

this.getField("Text104").readonly = true;

this.resetForm(["Text89", "Text90", "Text91", "Text92", "Text93", "Text94", "Text95", "Text96", "Text97", "Text98", "Text99", "Text100", "Text101", "Text102", "Text103", "Text104"]);

} else {

this.getField("Text89").readonly = false;

this.getField("Text90").readonly = false;

this.getField("Text91").readonly = false;

this.getField("Text92").readonly = false;

this.getField("Text93").readonly = false;

this.getField("Text94").readonly = false;

this.getField("Text95").readonly = false;

this.getField("Text96").readonly = false;

this.getField("Text97").readonly = false;

this.getField("Text98").readonly = false;

this.getField("Text99").readonly = false;

this.getField("Text100").readonly = false;

this.getField("Text101").readonly = false;

this.getField("Text102").readonly = false;

this.getField("Text103").readonly = false;

this.getField("Text104").readonly = false;

}
