I’m receiving the same error. can you offer support?
I am having the same issue with the error as OP.
I have set up the [select your-recipient] tag for 8 “contacts”.
When I try to use the [select* your-recipient] in the Mail To: field I get the syntax error result.
I also get the same result trying the [email* your-recipient] as well as [select* your-recipient “Name|name@emailexample.com” “Name2|name2@emailexample.com” “Name3|name3@emailexample.com”].
Any suggestions?
