Formatting text in business rules

A business rule isn't able to do this. 

You could do it with a no code approach by creating a process that starts on the record added or modified that reads the record, then sets the field value by combining the two values. The down side to this approach is that the user won't see this value until they refresh the page.

I realize you're after a no code approach, however, if you want to do this with code, you can add something like this to the methods of the page - this will set the name when the record is saved (assuming the field names are correct):

save: function() {
    var account = this.get("Account");
    var need = this.get("LeadType");
 
    if (account && need) {
        this.set("Name", account.displayValue + " - " + need.displayValue);
    }
 
    this.callParent(arguments);
}

(btw, I don't know why formatted code doesn't format code correctly on these forums, but the && is supposed to be &&)
