Validate if multi-select form field is empty

Adrian M_2w57lz

I have a multi-select dropdown in my confiforms form. I need to validate that it isn't empty when submitting the form.

Neither of these rules validate that in the rules macro as I'm able to submit the form:
MyList.asSize:0
MyList.asSize:<1

How can I validate that at least 1 selection was made.

!MyList:[empty]

But of course you need to have the validation rule that checks for "erroring condition", so it needs to be

MyList:[empty]

Thanks @Alex Medved _ConfiForms_ .

The validation works but a strange quirk shows up. There is only one validation rules macro. But the validation error message from it shows up twice on the top of the form. Any idea why that is and how to prevent it?

Do you have multiple validation rules?

Adrian M_2w57lz

There is only one rule. But two conditions in the same rule. The error message is "MyList is required".

I did a test by making a change to the message and the new message showed up twice.

Remove the value from the "Field name" parameter
