Hi,
I have created a survey that has one question. Here is a form (NewForm) of a survey:
If there are more than 2 check-boxes checked, it should alert the user and don't let him/her submit the form. Please, let me know, how should achieve this?
I have searched sources and was testing the limiting of the number of choices that a user can select in one Survey form. One of the sources and other one I have tried to modify and use to count the selected (checked) choices, but it didn't work as expected. I have also tried doing from this video, but I probably do something wrong. It seems that the code from this source could work, but it does not, I've tried modifications, but it was no use.
Would column validation function work here, or is jQuery/JS needed here?
