Unresponsive script issue

When trying to fill out a test form, I continously get a unresponsive script error. I have cleared my cache and I'm on the most current version of Firefox. I tried it on my phone and got the same error. 

Form - https://form.jotform.com/53520694584967

It was working earlier without problems. Not sure what happened. Please advise what I need to do to get this working again?

Hi,

I accessed the form you mentioned in this thread and I was able to replicate the issue. I was not able to fill up the form due to script errors.

The issues might be cause of your calculations or conditions setup. Let me further investigate the issue. I will get back to you as soon as I get a result.

Regards.

Hi,

As per further checking your form, the condition in Birth Month field might have cause the issue. 

You will noticed that you are updating the Birthday Month field base on the value of itself. Please try to disable or delete the condition and see if it will fix the issue. 

Do let us know if you need further assistance.
Regards.

If I need to move a response from one field to another - just coping it, not changing it in any way - what is the best way to do that? 

You can copy the value by simply adding the field in the calculation equation. Here's our guide for the calculation feature: http://www.jotform.com/help/259-How-to-perform-calculation-in-the-form.

If you would like to conditionally copy the value, you can add the calculation conditions, but it is recommended not to target the same field because this won't work.

Your form is crashing my browser as well so I would suggest changing your conditions.
