Submitted for customization screen

I have a jot form embedded on my site. 

When I press submit this text comes up ( See attached picture) 

Can I customize these words? That would be so great. Thanks!!!

Yes, you can customize the Thank You message and even redirect your users to a different Thank You page if you want, here is a guide that will help you to set up your custom Thank You page: https://www.jotform.com/help/211-Setting-Up-the-Thank-You-Page 

Hope this helps.
