Mandatory selection of Checkbox options

[sola2]

Hello, 

I have created a catalog item with serveral sections containing checkboxes. What I want to archieve is that for each section it is mandatory to check at least one of the check boxes.

I came accross an old post https://www.servicenow.com/community/sacramento-snug/catalog-item-sleight-of-hand-mandatory-selectio... which states to set the label as mandatory with a UI Policy and the conditions been that the checkboxes are false.

However, this is not working for me. Can someone help me with a more updated solution to this issue? Thank you in advance.

Hi, there are a few different ways you can accomplish this, and all of them rely on client scripts. Here's a very, very simple one that you can adjust, adding nested if's as required.

function onSubmit() {
   //Type appropriate comment here, and begin script below

   var box1 = g_form.getValue('boolean1');
   var box2 = g_form.getValue('boolean2);
   var box3 = g_form.getValue('boolean3');

   if(box1== 'false' && box2 == 'false' && box3 == 'false'){
	alert('Please select one of the three boxes.');
	return false;
   }
   else{
	return;
   }
   

 That being said, I'm unsure why the linked article's solution isn't working for you. I'd be happy to help if you'd like to pursue that solution instead. This is a silly idea, but does unchecking 'Reverse if false' change the behavior of your UI Policy?

Hello @Jon Hogland 

I tried unchecking the reverse if false option but nothing happens

Hi, did you try to implement the script I posted?
