You are storing the user selection in the database.

so my guess is your $vboptions[zh_load_type] = "select <somefield> from database where .. "
instead of that select, if you can tell me the page where its being called from

what we can do is something like

$vboptions[zh_load_type] = rand(1,23); or if I want say effect 1,2,,4,6,7 , then any random selection among this.
