Alternative Required Fields

I have a simple form with name, phone, email and message.

What I want is for name and then either phone or email or both (standard OR logic) to be required before the form can be submitted.

Does any one know of a way to do this?

Thanks

Fair enough, many thanks for getting back to me. in the meantime do you have any recommendations to achieve this?

i got this to work for me.

i have the same need. i have a form where the user must input either a home, work, or office number. i don't need all three just one or more.

how i got it work:
a required checkbox with conditional logic. the checkbox has home, office, and work as it's values.

three separate phone fields each marked required.

in the advanced tab of all of the phone fields i checked conditional logic and told the fields to show only if the corresponding check was placed on the checkbox above.

its quirky but it actually makes the form look cleaner and not having extra fields taking up real estate.

(i haven't had this form live but it worked great in a test.)
