Change Backcolor Of 'built' Control Number

I have a randomized table named tblRandomBoxes with the following data:

ID RandomID
1 4
2 5
3 2
4 6
5 1
6 3

I have 6 command buttons named command1,command2,command3, etc. and 6 Labels named Label1,Label2, Label3, etc. On Click of each command button, I want to lookup the ID based on the RandomID and set the backcolor of that label number to a different color.

ie) on command1 click me.Label4.backcolor = 39835

How can I 'build' the label number with the lookup? Here's the code I'm trying, but it doesn't recognize my 'built' label number:


Private Sub command1_Click()
Dim ctl As Control
ctl = "Label" & DLookup("ID", "tblRandomBoxes", "RandomID = 1")
Me.ctl.BackColor = 39835
End Sub

Thanks,

Sup
