i would like for this to be evaluated. i'm an es beginner, so analyze everything i do for mistakes.
i want each race with:

GeSHi (eventscripts):
es_keysetvalue WCSuserdata event_var(wcs_uid) symbiote 1

to increment a multiplier that can be used in the rest of the skills, like more damage, the more people with this key set.

GeSHi (eventscripts):
 
block wcs_symbiote
{
es_set symbiote_mult 0
es_xset wcs_exists 0
es es_xexists wcs_exists userid server_var(wcs_uid)
es es_xif (server_var(wcs_time) < 1) then es_xsetinfo wcs_exists 0
es es_xif (server_var(wcs_exists) = 1) do
    {
    es_xset wcs_exists 0
    es es_xexists wcs_exists key WCSuserdata server_var(wcs_uid)
    es es_xif (server_var(wcs_exists) = 1) do
        {
        es_xset wcs_exists 0
        es es_xexists wcs_exists key WCSuserdata server_var(wcs_uid) symbiote
        es es_xif (server_var(wcs_exists) = 1) do
            {
            es es_xsetinfo symbiotes 0
            es es_xkeygetvalue symbiotes WCSuserdata server_var(wcs_uid) symbiote
            es es_xif (server_var(symbiotes) = 1) do
            es_xmath symbiote_mult + 1
            es_keycreate WCStmp symbiotes
            es_keysetvalue WCStmp symbiotes multiplier server_var(symbiote_mult)
            }
        }
    }
}
