How do I allow users to select 3 courses in confiforms?

Peter Liu_b89z8f

A supervisor in different branch of my division asked me: to 

•        Create a new EWIL Fusion Classroom Training page using the content of the attached Word Document.  

Is there a way that you can create a voting capability on this new page that would allow users to pick their top 3 courses?  

 

I added ConfiForms Rules for Field Defnition and set validation rule in it. BUt it still allowed me to choose more than 3 courses

Earlier this morning, I thought about using multi-select drop down. But I don't know how to limit that option to 3

Also, I asked a computer scientist to help me. But he said the following:

yeah; i was experimenting with the validation rules with your page (copied to my personal) and was not able to get it to work. I am starting to think that _count doesnt do what i thought it would do

i tried validation rule(s) within the checkbox and also tried with the 'ConfiForm Rules for Field Definition' macro. no luck

Hi

(I suggest to remove the names of your colleagues from the question for privacy)

Using "ConfiForms Rules for Field Definition" macro with "Validate" as an action is a right thing to do

And the key is in the condition you put. You need to define a condition that "fails" the validation

Consider the following example (same approach works with ANY multi-value field - checkbox group, for example):
