why F5 give me this error

Hi,

Sorry just published a new version, I saw a mistake in the irule :

can't use empty string as operand of "!" while executing "if { (![whereis [IP::client_addr] country ] equals "EG") } { set allowed 1 }"

here the irule :

when HTTP_REQUEST { 
        set allowed 0 
        if { !([whereis [IP::client_addr] country ] equals "EG") } { 
            set allowed 1 
        }
        if { ($allowed == 0) and ([HTTP::path] ends_with "/register") } { 
            HTTP::redirect "http://www.test.com/register"
        } elseif { ($allowed == 1) and ([HTTP::path] ends_with "/register") } { 
            HTTP::redirect "http://www.test.com/login"
        } else {
            pool test
        } 
    }
