Search Button

[e4games]

so I want there to be a button (that looks like a submit button) that says search....when you click on the search button it either say you found something or say you didn't find something I want there to be a 9 in 10 chance that you didn't find anything and a 1 in 10 chance that you do.....when you get the message "you found something" I want it to display a code (could be anything like "aklj4j46lk" but it needs to then e-mail it to me and everytime that random code to change...how do I do that?
