I have tested your form and it is working in Firefox, but not inside of Chrome. I have also checked your form, and I noticed that you are using script block (source code) for embedding your form on website. We recommend using of iFrame code. You can try to replace source code with iFrame to see if that will solve your problem. In this article you can find out how to do it.
Hope this will help.
