Variable Picturebox

Erm, I have been trying this code by my self.
and it isn't working, so i need your help. please just help me on this

i have many pictureboxes with (indexes)

Code:

---

private TerType as Picturebox
set TerType = Mnt

Tertype(1).tag = "hey dude"

---

so Mnt is a picturebox with an array
Mnt(1 to 16)..


so in the end[basicly]
TerType(1).tag = Mnt(1).tag
