How Can Hide A Sign-up Option After X number of Sign-ups?

I have form which is being used to collect sign-ups for various sports camps. I want to close (hide) the sign-up option for each camp after I hit the sign-up limit for each camp.

As one form has several camps on it, I cannot use the "Disable form after x submissions option"

Is there a way to hold a variable outside of the form itself and then use the conditional logic to hide an option on a form when that variable (a counter) hits a certain point?

Thanks,

Ben

Please check my demo form: https://form.jotform.com/81688633371970

In the demo form, I have Gift Registry widget and Submission Counter widget.

The Gift Registry widget will count the available number Sign up until it is not available but it will not hide the Submit button. 

The Submission Counter widget will count the submission to your form and it will hide the Submit button once the condition is met (4 submissions only on my demo form) using the Show or Hide condition.

Please try submitting two submissions to my demo form to test it. You can also clone it by following this guide: https://www.jotform.com/help/42-How-to-Clone-an-Existing-Form-from-a-URL
