i've been looking through the documentation but can't find anything as to where the javascript goes in the forms.
help!
What JavaScript do you want to put in the form? Are you talking about the client side validation code?
i want to be able to disable or not display text fields depending on the selection in a drop down list
So I guess this is custom JS? In that case, you need to create a RawHTML div in the page contents bodycopy and place the JS there. You will also need to use a keyword to display the form, or specific form elements as required.
