this is a snippet from a project of mine
Code:
Dim A As Integer
Dim B As Integer
Dim C As Integer
A = Combo1.ListCount
B = Combo2.ListCount
C = Combo3.ListCount
Dim AX As Integer
Dim AY As Integer
Dim AZ As Integer
AX = Int(Rnd() * A)
AY = Int(Rnd() * B)
AZ = Int(Rnd() * C)
G1 = Combo1.List(AX)
G2 = Combo2.List(AY)
G3 = Combo3.List(AZ)
just change combo1 to list1
and take out all the extra stuff
G1 is a textbox by the way.
