..... Most people tend to not use caps on a regular basis so chances are they will be typing:
file_name.html
rather than the one with caps and will not be able to reach your page.
Hope that helps
Thanks Jo Ann, an oversight on my part!
I will rename the form as order_form but not just yet, as the link in my previous post wont work if I alter it and the post wont make sense.
I have tried clicking 'Editing Post' but it says..... Whoops, we can't seem to find that page!
Thanks again.
