isset/required validation bug

I think the error variable should be set before building the error message. Else the error variable will be set with the text define in set_fields().

Code:

// Set the error variable name.  Example: $this->username_error
        $error = $field.'_error';
        
        // Build the error message
        $field = ( ! isset($this->_fields[$field])) ? $field : $this->_fields[$field];
        $message = sprintf($line, $field);
        
        // Set the error variable.
        $this->$error = $this->_error_prefix.$message.$this->_error_suffix;
        
        // Add the error to the error array
        $this->_error_array[] = $message;
