JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
As a free plan user, you only have 100 submissions limit per month. Either you wait for the 1st day of the month for the counter to reset it back to zero or you upgrade your plan. Here's the pricing page if you're interested: https://www.jotform.com/pricing
If you're asking about how to limit the submissions based on the date or the number of submissions then you need to adjust it in the Preferences. Here's a guide:
1. Go to Preferences, in the Form Builder.
2. In the Preferences wizard, go to General tab and then change the Status to Disabled on Submission limit.
3. After that, you can change your preferred Submission Limit and Warning message.
