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.
I took a look at your submissions and you have one submission that has a file of 150.84 MB attached to it, so you have went over the quota that you have for your free package.
You will need to either remove the file or to upgrade to a new package.
If you want to remove the file you can do so by removing the submission.
If you want to upgrade you can do so by switching to another plan.
For that please go to this page http://www.jotform.com/pricing
Do let us know if you need any further assistance.
