Selectable Recipient error

Hello,

I’m trying to make a form with different recipients and you have made a guide how to do so here.

My problem is when I enter [your-recipient] in the To field in my form settings it says “This field has syntax errors.”. I have tried to disable the configuration validator, but the form still doesn’t work. When I try to send an e-mail I get the error “There was an error trying to send your message. Please try again later.”

What am I doing wrong?
