Form works in Firefox but not IE - object definition problem?
Hi - I'm quite a beginner at this and have been writing what to me is a faily complicated form - the key characteristic of the form is that the contents of subsequent drop down boxes varies depending on the user input in the previous one.
The form works fine in Firefox - but not in Internet Explorer 7 or 8 - but it did in 6. It doesn't work in Safari either.
The error code I'm getting from IE8 is:
Message: 'document.free.leveltwo.options' is null or not an object
Message: 'document.free.levelthree.options' is null or not an object
Message: 'document.free.levelfour.options' is null or not an object
Message: 'document.free.levelfive.options' is null or not an object
I think I need to define them as objects first - but I'm unclear how to do this - and have tried with out sucess.
The form is at:
and notes on it's purpose is here (you may need this to understand what I'm trying to do)
Any advice greatly appreciated - and please explain it simply I'm quite an ignoramus at this - and am surprised I've got it to work so far!
