How can I limit submisions?

how do i control the limit of how many some one can vote?

From how I understood it, your aim is to limit the submissions (or votes) done on your form. To achieve that, you have 2 options to choose from:

1. Limit the submissions using the user's/visitor's IP or browser cookie.

2. Or setup a Unique Question on your form.
