Sound Activated When A Search Result Is Found

so, although I don't use any of the technologies you have listed, here is what I would do, from a logic standpoint (I assume you would be doing an onload event for the sound.  Regardless, just plug in your code.  It should work):

• You start off by having, say, A.sound and B.sound in your file system.  In your call to the file, you have a variable that holds either "A" or "B", depending on what kind of drug.
• You determine the type of drug, based on type, you assign variable "A" or "B" like so:
  <?php echo $drugType; ?>.sound (where $drugType is either "A" or "B"

If you are using a database, then you get the value of the "drugType" column and again, based on type, assign the necessary variable.

That should do it.  If I don't understand, break it down for me and whoever happens to read this post as well.
