Scratch

Here are a couple of possibilities.  (1) your script actually reads: go to the start position and if, at that position, you're touching Sprite 2, then do something.  But what are the odds that right when the enemy is at its start position it's going to be touching the bullet?  Probably not. So it might work to rewrite the script so that *whenever* the enemy touches Sprite 2, then it would do something. The "forever" command might work for that. ______(2) in my limited experience the "glide" command can't really be interrupted along the way.  (It glides, and *then* it checks to see if it's touching something.)  It seems to work better to use a "repeat" where into each repetition you build the condition "if touching Sprite 2."  That way the script constantly checks to see if Sprite 2 is being touched. So you would have a script that says:
     Repeat ()
          Move 5 steps
          Wait 0.1 seconds
          If touching Sprite 2
                 go to.....
               else
                 go to.....
Sorry I haven't used the nice Scratch blocks to write the script but I haven't learned how yet!  :-/
