Garbo is right on. The userform is referred to as "Me". If you want to keep the process simple for changing the background color of the labels then I recommend naming them about all the same. For example name them:
Label1, Label2, Label3, Label4, etc.
Just make sure you don't miss a number.
This makes it so you don't have to write tons of code to change the back color and instead you can do it something like this.
Dim x As Integer
For x = 1 To 22
Me.Controls("Label" & x).BackColor = RGB(51, 102, 255)
Next x
This is a lot simpler than having to write
Me.Label1.BackColor = RGB(51, 102, 255)
... all the way to...
Me.Label22.BackColor = RGB(51, 102, 255)
I'd rather write 4 simple lines of code instead of 22 lines of code. Plus, I don't have to change 22 lines if I ever decide I want it a different color. I only have to change 1 line instead.
