How can I prevent submissions with the same entry?Asked by BlitzSports on February 17, 2015 at 07:40 PM
I've gone to form limits and chosen a field to not allow previously entered data. However, when I tested to make sure it would work, it still allowed me to enter the same data into that field and successfully submit. I want to cut down on submissions by limiting nominations for the same person on a form
Submissions same entry form limits limiting
I can see that you have correctly setup the Strict IP Address Check for Unique submission of your jotform http://www.jotform.us/form/50475758093161
When I test submitted the form, I was able to see the strict/unique submission working.
I can no longer submit the same form the 2nd time around
There are cases when IP checked will not work on some network. Like those network that assign random IP address, or configuration that block IP checked. This is usually the possible reason why this feature will not work.
Can you confirm that you were able to reproduce the issue on your own network? Or was it from a different user of your form.
Please inform us if issue persist.
