How to disable my form tonight at a certain time?

Hi there,

I'm trying to put an expiration date/time in my form...I would like it to expire tonight at 7pm.

I went into form limits, and added "2016-02-25 19:00" but it gives me an error, saying that the date is not later than today, and so it will disable the form NOW. I don't want it to disable NOW; I want it to disable at 19:00.

For now I have used "2016-02-26 00:00" but I would like to change it to "2016-02-25 19:00"

Can you help me do this?

Thank you very much!

It looks like it worked. I just looked at your form and it is looking good:

Okay, now I'm going crazy. I specifically changed this to 2/26/16 0:00. And I also made some changes to the Warning message that are not there anymore. How could my changes get lost like this? I know that I hit "close settings", and the form is always saving automatically, right?

The form should indeed save automatically.  However, if your session had timed out or the browser was closed before the changes were saved, they may not have applied to your form.  Any time you make a change, I would recommend manually saving by pressing the "Save" button.
