How do you put a link on a warning message?

We created a waitlist form for our camp enrollment.  Once the camp is full, Warning message will link it to the waitlist form.  Is this possible to do or are there other way to do it.

Thank you.

It seems like the only way is to set the Form limits message with instructions to redirect on the other form URL.

I'm trying to use the Submission Counter widget and conditional logic on it, but it doesn't work.

However, there's still another way, if you are embedding the form on a website and you are familiar with Javascript, you can try getting the number of submissions of the form using our API, here's our API documentation: http://api.jotform.com/docs/#form-id-submissions. After that, you can create a custom script to count how many are there, hide the rest of the form and show the warning message. You can add the custom script on your form's full source code.

I hope that gives you an idea on how to proceed.
