Can I see your form?

it's not yet published unfortunately still working on it and the site it belongs on

How are you testing it?

Thank You Eric,

I've gotten it working. I needed to delete the original files off the server first. Just exporting again wasnt working, it can't have been overwriting it correctly.

So the last solution worked?

Yes, the last solution on its own worked with the first code removed.

It loads a little low, in that the 'please check your order' message is already part way off the screen and it just shows the bottom half and the submit button, but that's much better than reloading right to the very top of the page and scrolling past the entire form.

What Im trying to avoid is customers not fully completing the order process because they've not seen the second stage of the form and leading to complaints and this felt like it could have been very likely with the page reloading to the very top.

You can customize this a little by adding in your own custom div with a unique ID. Then adjust the code to scroll to that div.
You can then move the div around in the confirmation and find the sweet spot that scrolls correctly.
$(window).scrollTo('#customid');

<div id="customid"></div>

Ah Brill Eric, Thank You

I didnt think of that

Your welcome. Thats what the forum is all about. Great place to bounce ideas off other users because everyone looks at things different. The world would be pretty boring if they didn't.
