Fill Text Box Based on Selection Made in Drop Down

So, I've found a few suggestions in the forum on how to do this, but I can't make it work, and my situation is much simpler than all the other conversations that I can find.

I have a Drop Down menu ("Banked Weeks") that contains two options: "No" and "Yes".

No is the default selection and remains there at all times, but the user can switch it to Yes.

I then have a text box ("How Many") that I want to autofill with "None" when "No" is selected and be fillable - and become required - when "Yes" is selected.

Any help would be appreciated.

Sorry, in the first line it should be "How Many", not "Banked Weeks"...

As the custom validation script of the drop-down field enter the following code:

var f = this.getField("Banked Weeks");

f.readonly = (event.value=="No");

f.required = (event.value=="Yes");

f.value = (event.value=="No") ? "None" : "";

So, that did what you told it to, but that's not exactly what I wanted to happen...

The drop down doesn't need to be read only ever.

And I would like the Text Field "How Many" to become required and fillable when the drop down "Banked Weeks" says "Yes"

While, when the drop down says "No", the text field "How Many" auto fills with 'None'.
