Show row when a specific choice is made from a dropdown box

[TheJay]

I have dropdown boxes in C8 and C13, pulling data from =$C$9:$C$11 and =$C$14:$C$16 respectively. Each column has three options. M, W or Wy. I would like for row 10 to display when Wy is selected from C8, so that a message can be shown in C10 and row 15 when Wy is selected from C13, so a message can be shown in C15.

I suspect that this can be achieved with VLOOKUP but I'm not sure. When one of the other two choices is made from these dropdown boxes, the row should hide again.

Thanks.
