Access to VIP by irule for matching a header value OR allowing ips using data-group

thanks, so I have done this (added the pool default and else for drop) but it gives me some errors in the GUI -

when HTTP_REQUEST { Check if http_header contains hex code or the client IP is not in the allow list if { !([HTTP::header "name_of_header"] equals "3196E8D30330CA17238FAS013036" or [class match [IP::client_addr] equals WHITELIST])} { pool default else { if neither value matches drop traffic drop } }
