What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
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.
You can take advantage of our conditional logic (Show/Hide Condition) to hide a section of a form and only show it based on the correct information supplied. For example: http://www.jotformpro.com/form/42813259506961. Enter "123" in the passcode box to reveal the submit button.
Here's the conditional logic settings:
