How to avoid manually scrolling up to see the Thank You message?

When my customer has made an order, and goes to review my order and submit, page stays at button, so it looks like a blank page, untill you scroll up the page, can I make the page go up automatically, when customer choose review and submit button ?

Hope it makes sence :)

They have to scroll up because of the Iframe's height. You could shorten the Iframe's height, and enable the scrolling property, example:

I can`t change the height, since it won`t show corretly on mobile devices, and scrolling is the same issue, it gives problems on moblie devices when on. Is there no other way around this problem ? 

You may create your own Thank You page within your site, and redirect the user there after submission: https://www.jotform.com/help/211-Setting-up-the-Thank-You-Page 

Thank you, that might work, but I can`t see that it is possible for me to insert what the customer have ordered on here ? 

I only seem to be able to move name, adress and so on over to this page, but I need to show the customer what he ordered, is that possible on a external link page ?

The field {names} will not work on the external thank you pages. This is possible to post submission data with a special Send Post Data option, but a custom programming is required to process that data.

Have you tried to use a complete iFrame embed code on the web page? There is a chance that the scrolling will work with the standard code.
