Need help with dice pictures showing on buttons

Hello all, I am new here so I'm not sure if this is the right place. I am currently trying to make my final project for vb class and I've been stumped for at least five days on this code. I'm trying to make a program to emulate the game "farkle". My problem is that when I press the "roll" button on my form, its supposed to show six randomly generated dice on six buttons. My problem is that no matter what I do, it won't show on the dice. Here is my code. I condensed it because I am on my phone and there is no internet at my grandmas house:

Dim dicerand1 As Integer
...
Dim Dicerand6 As Integer

Dim diceRandom As New Random

Dicerand1 = dicerandom.next(1, 7)
...
Dicerand2 = dicerandom.next(1, 7)

'=====Case for the first random dice=====
Select Case diceRand1
	 Case 1
		   BtnShowDice1.backgroundImage = My.Resources.small_dice_1
	  ...
	 Case 6
		   Btnshowdice1.backgroundImage = My.resources.small_dice_6
	  End Select

...
	  '=====case for the sixth random dice=====
	  Select case dicerand6
			Case 1
				 Btnshowdice6.backgroundImage = My.Resources.small_dice_1
			...
			Case 6
				 Btnshowdice6.backgroundImage = my.resources.small_dice_6
			End Select
