Prefabs not Instantiating in the Propper Place

I'm creating a music game to help music students learn the notes of the musical staff. When a student selects the correct note, the note should disappear and a prefab will take its place. I'm having a problem with prefabs not spawning at the correct position of the note. The prefabs spawn at it's default transform position instead of where the note position is. It's worth mentioning that this is a 2D game. This is what I have:

Code (CSharp):

1.  if (button.tag == noteList[notePositionOnStaff].tag)
2. {
3. Instantiate(scoreAnimation, new Vector3(noteList[notePositionOnStaff].transform.position.y, noteList[notePositionOnStaff].transform.position.y, 0.0f), Quaternion.identity);
4. }

 

It's also worth mentioning that line 3 above is a hairy line of code.

Rewrite it so you an inspect the values and figure out why they are wrong.

I figured out the problem. I had an animator that was playing an animation that set the position back to the position the animation was created. BTW thanks for the info about the hairy code. I'm always looking for ways to improve my skills.
